## Executive Summary

**Mana-Loop** is a browser-based incremental/idle game with a 30-day time loop mechanic. Players gather mana, practice disciplines, climb a 100+ floor spire, defeat procedurally-tiered guardians, sign pacts, enchant equipment, summon golems, and prestige for permanent progression.

**Key Differentiators:**
- 3-class Attunement system (Enchanter, Invoker, Fabricator)
- Equipment-based spell system (spells come from enchanted gear and learned spells)
- Practice-based Discipline system — no discrete skill levels, only continuous XP growth
- Time pressure through the incursion mechanic (starts day 20)
- Guardian progression: base (10-80) → composite (90-160) → exotic (170-240) → combo bosses (250+, 8 tiers)
- Guardian pacts provide permanent multipliers that persist through prestige
- No backend — pure client-side with localStorage persistence

**Code Architecture:** 8 modular Zustand stores, crafting actions, discipline data, and constants. No legacy store files remain.

## Core Game Loop

### Primary Loop (Within Each Run)

```
┌─────────────────────────────────────────────────────────────┐

## Mana System

### Mana Types Hierarchy

    ├──▶ Base Elements (7) ─────────────────────────────────────┐
    │    Fire*, Water*, Air*, Earth*, Light*, Dark*, Death*     │
    │    *Locked at start — must be unlocked via guardian pacts │
    │                                                           │

         Plasma = Lightning + Fire + Transference                │
```

Only **Transference** is unlocked at start. All other elements must be unlocked through guardian pacts.

### Mana Formulas

**Maximum Raw Mana:**
```
base = 100 + (manaWell_prestige × 500) + disciplineMaxManaBonus
final = (base + equipmentMaxManaBonus) × equipmentMaxManaMultiplier
```

**Maximum Elemental Mana:**
```
elementMax = (10 + (elemAttune_prestige × 25)) × elementCapMultiplier
```

**Base Regeneration (per hour):**
```
base = 2 + (manaFlow_prestige × 0.5)
temporalMult = 1 + (temporalEcho_prestige × 0.1)
regen = base × temporalMult + attunementRegen + disciplineRegenBonus
final = (regen + equipmentRegenBonus) × equipmentRegenMultiplier
```

**Effective Regen (per tick):**
```
effectiveRegen = max(0, baseRegen × (1 - incursionStrength) × meditationMultiplier - totalConversionPerTick)
```

**Meditation Bonus:**
```
Base: 1 + min(hours/4, 0.5)  →  up to 1.5× after 4 hours
```

**Attunement Mana Conversion:**
- Enchanter: Raw → Transference at 0.2/hour base (scales with 1.5^level)
- Fabricator: Raw → Earth at 0.25/hour base (scales with 1.5^level)
- Invoker: No automatic conversion (gains mana from pacts)

### Mana Conversion Cost
- **100 Raw Mana = 1 Elemental Mana** (for base elements)
- Composite/Exotic elements are crafted, not converted

---

## Time & Incursion System

### Time Constants

| Constant | Value | Description |
|----------|-------|-------------|
| `TICK_MS` | 200ms | Real time per game tick |
| `HOURS_PER_TICK` | 0.04 | Game hours per tick |
| `MAX_DAY` | 30 | Days per loop |
| `INCURSION_START_DAY` | 20 | When incursion begins |

### Time Progression
- 1 real second = 5 game hours (at 5 ticks/second)
- 1 game day = 24 game hours = 4.8 real seconds
- Full 30-day loop ≈ 2.4 real minutes

### Incursion Mechanic

```
if (day < 20): incursionStrength = 0
else:          incursionStrength = min(0.95, (totalHours / maxHours) × 0.95)
  where totalHours = (day - 20) × 24 + hour
        maxHours   = (30 - 20) × 24 = 240
```

Reduces mana regeneration by `(1 - incursionStrength)`. Starts at 0% on Day 20, reaches 95% by Day 30.

---

## Spire & Floor System

### Floor Element Cycle

```
FLOOR_ELEM_CYCLE = [fire, water, air, earth, light, dark, death]
element = FLOOR_ELEM_CYCLE[(floor - 1) % 7]
```

### Floor HP Formulas

**Normal floors:**
```
HP = floor(100 + floor × 50 + floor^1.7)
```

**Guardian floors:**
```
HP = floor(5000 × (floor/10) ^ (1.1 + floor/200))
```

### Room Types

| Room Type | Chance | Description |
|-----------|--------|-------------|
| **Guardian** | Every 10th floor | Boss encounter |
| **Puzzle** | 100% on every 7th floor (except guardian floors) | Attunement-themed trial |
| **Swarm** | ~12% | 3–7 weak enemies |
| **Speed** | ~10% | Single enemy with elevated dodge chance |
| **Combat** | ~68% (default) | Single enemy, normal combat |
| **Recovery** | ~4% | 1 hour; grants 10× mana regen & conversion |
| **Treasure** | ~3% | 1 hour; grants 2–15 random items |
| **Library** | ~3% | 1 hour; grants discipline XP at 25× rate |

### Puzzle Room Types
- Single attunement: `enchanter_trial`, `fabricator_trial`, `invoker_trial`
- Dual attunement: `hybrid_enchanter_fabricator`, `hybrid_enchanter_invoker`, `hybrid_fabricator_invoker`
- Base progress: 1.5–2% per tick; attunement bonus: 2.5–3% per relevant attunement level

### Enemy Modifiers (Non-Guardian Floors)

| Modifier | Min Floor | Effect | Scaling |
|----------|-----------|--------|---------|
| **Armored** | 5+ | Armor (damage reduction) | 10%–45%, scales with floor |
| **Agile** | 12+ | Dodge chance | 20% base + 0.4%/floor, max 55% |
| **Mage** | 15+ | Barrier (shield HP) | Up to 40% of max HP, recharges 5%/tick |
| **Shield** | 10+ | One-time shield | 15% of max HP |
| **Swarm** | 8+ | Multiple weaker enemies | 3–7 enemies, each 35% HP |

Max 2 modifiers per enemy. Low floors (1–4) get no modifiers.

### Armor Scaling (Non-Guardian)
- No armor below floor 10
- Armor chance: `min(0.5, (floor - 10) × 0.01)`
- Armor value: 5%–25% damage reduction, scaling with floor progress

---

## Combat System

### Spell Casting Mechanics

```
castProgress += HOURS_PER_TICK × spellCastSpeed × attackSpeedMultiplier
When castProgress >= 1: deduct mana, deal damage, reset progress
```

### Damage Calculation

```
baseDmg = spell.dmg + disciplineBaseDmgBonus
pctMult = 1 + disciplineDmgMult
elemMasteryMult = 1 + (elementalMastery × 0.15)
guardianBaneMult = 1 + (guardianBane × 0.2)  [guardian floors only]
rawDmgMult = 1 + boonRawDamage / 100
elemDmgMult = 1 + boonElementalDamage / 100

damage = baseDmg × pctMult × elemMasteryMult × guardianBaneMult × rawDmgMult × elemDmgMult
damage *= getElementalBonus(spellElement, floorElement)

// Critical hit
critChance = disciplineCritChance + boonCritChance / 100
critDmgMult = 1.5 + boonCritDamage / 100
if (random() < critChance) damage *= critDmgMult

// Special modifiers
if (floorHP / floorMaxHP < 0.25) damage *= 2    // Executioner
if (rawMana < maxMana × 0.5) damage *= 1.5      // Berserker

// Armor reduction
effectiveArmor = max(0, enemyArmor - armorPierce)
damage *= (1 - effectiveArmor)
```

### Elemental Effectiveness

| Condition | Multiplier |
|-----------|------------|
| Spell opposes floor element (super effective) | 1.50× |
| Spell matches floor element | 1.25× |
| Spell's opposite matches floor (not very effective) | 0.75× |
| Neutral / Raw mana spells | 1.00× |

**Element Opposites (bidirectional):**
```
Fire ↔ Water     Air ↔ Earth     Light ↔ Dark
Frost ↔ Fire
```

**Element Counters (directional):**
```
Lightning → Water    Earth → Lightning
```

**Composite Element Counters (bidirectional):**
```
BlackFlame ↔ Frost, Water, Light
Radiant Flames ↔ Frost, Water, Dark
Miasma ↔ Air
Shadow Glass ↔ Light
```

- Note: Floor 100 guardian element is `sand+fire+earth` (composite components), Floor 140 is `sand+earth+water`, Floor 150 is `lightning+fire+air`

#### Tier 3 — Exotic Elements (Floors 170–240)

| Floor | Element | Armor | Pact Mult | Pact Cost | Pact Time |
|-------|---------|-------|-----------|-----------|-----------|
| 170 | crystal | 35% | 5.5× | formula | 37h |

Floors 90–240 have procedurally generated names via `generateGuardianName()`.

#### Tier 4 — Dual Element Pairs (Floors 250–280)

Nine dual-element combinations cycle every 10 floors:

| Combo Index | Elements | Theme |
|-------------|----------|-------|
| 0 | fire + water | Steam |
| 1 | fire + air | Smoke |
| 2 | water + earth | Mud |
| 3 | light + dark | Twilight |
| 4 | death + light | Undeath |
| 5 | fire + death | Hellfire |
| 6 | water + dark | Abyssal |
| 7 | air + light | Radiant wind |
| 8 | earth + death | Fossil |

#### Tiers 5–8 — Scaling Combo Bosses (Floors 290+)

- **Tier 5 (290–330)**: Dual composite + components
- **Tier 6 (340–380)**: Exotic + components
- **Tier 7 (390–430)**: Exotic + composite + components
- **Tier 8 (440+)**: Full fusion — 1 exotic + 2 composites + all base elements

**Scaling (per tier):**
```
armor           = min(0.7, 0.30 + floor_increment × 0.002-0.003)
pactMultiplier  = 7.5+ (scales with tier)
pactTime        = 20+ hours (scales with tier)
damageMult      = 3.5+ (scales with tier)
insightMult     = 3.0+ (scales with tier)
```

Combo guardians grant boons to both elements (+10% each) and dual-aspect perks (+20% effectiveness to both element spells). Names generated from combined prefixes (e.g., "Ignis-Aqua the Warden").

### Guardian HP Formula (All Tiers)
```
HP(floor) = floor(5000 × (floor/10) ^ (1.1 + floor/200))
```

### Guardian Combat Effects

| Element | Passive Effect |
|---------|---------------|
| fire | burn (0.1) |
| water | armor_pierce (0.15) |
| air | cast_speed (0.05) |
| earth | armor_pierce (0.2) |
| light | crit_chance (0.1) |
| dark | crit_damage (0.15) |
| death | raw_damage (0.1) |
| transference | cost_reduction (0.25) |
| metal | armor_pierce (0.2) |
| sand | slow (0.25) |
| lightning | chain (2) |
| crystal | reflect (0.15) |
| stellar | night_bonus (0.3) |
| void | resist_ignore (0.4) |
| frost | freeze (0.2) |
| blackflame | curse+burn (0.15+0.15) |
| radiantflames | blind+burn (0.15+0.1) |
| miasma | corrosion+poison (0.2+0.15) |
| shadowglass | armor_pierce+pierce (0.3+0.25) |
| soul | defense_pierce (0.5), mana_drain (0.2) |
| time | slow (0.3), temporal_snap (0.15) |
| plasma | chain (3), burn (0.1) |

### Guardian Boons (on pact)

Each guardian grants 2 boons from: `maxMana`, `manaRegen`, `castingSpeed`, `elementalDamage`, `rawDamage`, `critChance`, `critDamage`, `spellEfficiency`, `manaGain`, `insightGain`, `prestigeInsight`.

### Pact Ritual
1. Defeat guardian → floor added to `defeatedGuardians`
2. Start ritual: costs raw mana + time (guardian-specific)
3. Progress increases by `HOURS_PER_TICK` per tick
4. On completion: floor moves to `signedPacts`, boons applied
5. Pact slots limit simultaneous signed pacts (starting 1, upgradeable)

### Victory Condition
No specific victory condition is currently defined. The loop ends when day 30 is reached (or floor 30 for early completion). A victory condition with a ×3 multiplier is awaiting design finalization.

Signed pacts do **NOT** persist through prestige — the player must re-defeat Guardians and re-sign pacts each loop.

---

## Attunement System

Attunements are class-like specializations that unlock discipline pools and grant unique capabilities.

### The Three Attunements

#### 1. Enchanter (Right Hand) — Starting

| Property | Value |
|----------|-------|
| **Slot** | Right Hand |
| **Primary Mana** | Transference |
| **Raw Regen** | +0.5/hour base |
| **Conversion** | 0.2 raw→transference/hour |
| **Unlock** | Starting attunement |

**Disciplines:** 10 disciplines across 4 files (core: 4, utility: 2, spells: 3, special: 1)
**Capabilities:** Enchanting & disenchanting equipment

#### 2. Invoker (Chest) — Locked

| Property | Value |
|----------|-------|
| **Slot** | Chest |
| **Primary Mana** | None (gains from pacts) |
| **Raw Regen** | +0.3/hour base |
| **Conversion** | None |
| **Unlock** | Defeat first guardian |

**Disciplines:** 2 disciplines (Spell Casting, Void Manipulation)
**Capabilities:** Form pacts with guardians, access guardian powers

#### 3. Fabricator (Left Hand) — Locked

| Property | Value |
|----------|-------|
| **Slot** | Left Hand |
| **Primary Mana** | Earth |
| **Raw Regen** | +0.4/hour base |
| **Conversion** | 0.25 raw→earth/hour |
| **Unlock** | Prove crafting worth |

**Disciplines:** 5 disciplines (Golem Crafting, Crafting Efficiency, Study Fabricator Recipes, Study Wizard Equipment, Study Physical Equipment)
**Capabilities:** Golem crafting, gear crafting, Earth shaping

### Attunement Leveling

```
Level 2: 1,000 XP
Level 3: 2,500 XP
Level 4+: 1000 × 2^(level-2) × 1.25
Max Level: 10

regenMultiplier  = 1.5^(level - 1)
conversionRate   = baseRate × 1.5^(level - 1)
```

---

## Discipline System

Disciplines replace the old skill system entirely. There are no discrete levels — disciplines grow **continuously** through practice. The player activates a discipline and it drains mana each tick in exchange for permanent stat growth within the run.

### Core Concept

> The more you practice a discipline, the stronger its effect — but the more mana it costs to maintain.

- **XP** accumulates each tick the discipline is active and has enough mana to drain
- **Stat bonus** grows as a power curve of XP (never resets within a run)
- **Mana drain** also increases with XP — mastery has a cost
- **Perks** unlock at XP thresholds, granting bonus effects

### Formulas

**Stat Bonus (continuous):**
```
StatBonus = baseValue × (XP / scalingFactor)^0.65
```

**Mana Drain Per Tick:**
```
ManaDrainPerTick = drainBase × (1 + (XP / difficultyFactor)^0.4)
```

### Concurrent Discipline Limit

```
concurrentLimit = min(1 + floor(totalXP / 500), 4)
```

Players start with 1 active discipline slot. As total XP across all disciplines grows, additional slots unlock (max 4 total).

### Perk Types

| Type | Behaviour |
|------|-----------|
| `once` | Unlocks permanently when XP reaches `threshold` |
| `capped` | Grants stacking bonus tiers; each tier requires another `interval` XP beyond `threshold` |
| `infinite` | Repeating bonus — a new stack every `interval` XP past `threshold` (no cap) |

### Discipline Pools (64 Total)

| Pool | File | Count | Requires |
|------|------|-------|----------|
| Base | `base.ts` | 3 | None |
| Elemental Attunement | `elemental.ts` | 21 | None |

### Discipline Lifecycle

```
1. Player opens Disciplines tab → sees available disciplines for their attunements
2. Player activates discipline (costs nothing up-front; requires mana type unlocked)
3. Each game tick:
   a. ManaDrain deducted from mana pool
   b. If insufficient mana → discipline auto-pauses
   c. If sufficient mana → disc.xp += 1; stat bonuses recomputed
4. Player can manually pause/resume disciplines
5. On loop end, XP resets (stat bonuses are per-run, not permanent)
```

### Equipment Instance Structure

```typescript
interface EquipmentInstance {
  instanceId:     string;
  typeId:         string;
  name:           string;
  enchantments:   AppliedEnchantment[];
  usedCapacity:   number;
  totalCapacity:  number;
  rarity:         'common' | 'uncommon' | 'rare' | 'epic' | 'legendary' | 'mythic';
  quality:        number;  // 0–100
}
```

### Enchantment Process (3 Stages)

#### Stage 1: Design
- Select effects from unlocked pool (`data/enchantments/`)
- Name the design, choose equipment type
- Time: 1h base + 0.5h per effect stack
- Dual design slot available with Enchant Mastery special
- 10% chance per tick for instant completion (Instant Designs special)
- Implemented in `crafting-design.ts` / `design-actions.ts`

#### Stage 2: Prepare
- Equipment must be equipped
- **Removes all existing enchantments** (confirmation dialog if enchanted)
- Mana cost: `totalCapacity × 10`
- Time: `2h + floor(totalCapacity / 50)` hours
- Auto-transitions to Meditate on complete
- **ONLY stage where explicit disenchanting is possible**
- Implemented in `crafting-prep.ts` / `preparation-actions.ts`

#### Stage 3: Apply
- Equipment must have "Ready for Enchantment" tag
- Select a saved design to apply
- Time: `2h + sum(stacks)` hours
- Mana per hour: `20 + 5 × sum(stacks)`
- Free enchant chances: Enchant Preservation (25%), Thrifty Enchanter (10%), Optimized Enchanting (25%)
- Pure Essence special: effects with base cost < 100 get 1.25× stacks
- Cannot re-enchant already enchanted gear (must Prepare first)
- Implemented in `crafting-apply.ts` / `application-actions.ts`

### Enchantment Effect Categories

| Category | File | Equipment Types | Example Effects |
|----------|------|-----------------|-----------------|
| **Mana** | `mana-effects.ts` | Most | `mana_cap_50`, `mana_regen_1`, `click_mana_1`, `{element}_cap_10/25/50` |
| **Combat** | `combat-effects.ts` | Casters, Hands | `damage_5`, `damage_10`, `damage_pct_10`, `crit_5`, `attack_speed_10` |
| **Elemental** | `elemental-effects.ts` | Casters, Swords | `sword_fire`, `sword_frost`, `sword_lightning`, `sword_void` |
| **Special** | `special-effects.ts` | Various | `spell_echo_10`, `guardian_dmg_10`, `overpower_80`, `first_strike`, `combo_master`, `adrenaline_rush` |
| **Utility** | `utility-effects.ts` | Most | `meditate_10`, `study_10`, `insight_5` |
| **Spell** | `spell-effects/` | Casters only | `manaBolt`, `fireball`, `inferno`, `pyroclasm`, `stellarNova`, etc. (~40+ spells) |
| **Defense** | `defense-effects.ts` | — | Placeholder (empty) |

### Capacity & Stacking
- Each equipment type has `baseCapacity` (15–80)
- Each enchantment effect has `baseCapacityCost` per stack
- **Stacking cost:** each additional stack costs 20% more: `cost × (1 + i × 0.2)` for stack index `i`
- Efficiency bonus reduces total cost: `totalCost × (1 - efficiencyBonus)`

### Disenchanting
- Only possible during **Prepare stage** (or via explicit disenchant action)
- Recovery rate: `0.1 + disenchantLevel × 0.2` (base 10% + 20% per level)
- Clears all enchantments, resets `usedCapacity` to 0

### Starting Equipment

| Slot | Item | Enchantment | Capacity |
|------|------|-------------|----------|
| Main Hand | Basic Staff (2H) | Mana Bolt spell | 50/50 |
| Body | Civilian Shirt | None | 0/30 |
| Feet | Civilian Shoes | None | 0/15 |

## Golemancy System

### Golem Slots

```
slots = floor(fabricatorLevel / 2)   [minimum 0]
Level 2: 1 slot
Level 4: 2 slots
Level 6: 3 slots
Level 8: 4 slots
Level 10: 5 slots
```

### Component-Based Construction

Golems are designed by assembling **three mandatory components** plus optional enchantments:

| Component | Role | Count | Examples |
|-----------|------|-------|----------|
| **Core** | Power source: mana types, capacity, regen, upkeep, duration | 4 (Basic, Intermediate, Advanced, Guardian) | Basic Core (Earth only), Guardian Core (all guardian mana types) |
| **Frame** | Combat stats: damage, speed, armor pierce, magic affinity, special | 7 (Earth, Sand, Frost, Crystal, Steel, Shadowglass, Crystal-Steel Hybrid) | Earth (balanced), Shadowglass (fast + AoE), Crystal-Steel Hybrid (guardian constructs) |
| **Mind Circuit** | Behavior: basic attacks, spell casting, spell cycling | 4 (Simple, Intermediate, Advanced, Guardian) | Simple (basic only), Guardian (cycle all spells) |
| **Enchantments** | Sword effects on basic attacks (optional) | 8 | Burn, Slow, Shock, Weaken, Armor Pierce, Crit Chance |

**Player upkeep formula:**
```
Upkeep per hour = Core.manaRegen × 2
```

Golems last `Core.maxRoomDuration` rooms (3–8 depending on core tier). Stats are derived from components via `computeGolemStats()`.

---

## Prestige/Loop System

### Loop End Conditions

| Condition | Result |
|-----------|--------|
| Day 30 reached | Loop ends, gain insight |
| Floor 30 reached | Loop ends early, gain insight |

### Insight Formula

```
skillBonus = 1 + (insightHarvest × 0.1) + disciplineInsightBonus
boonInsightMult = 1 + boonInsightGain / 100
mult = (1 + insightAmp × 0.25) × skillBonus × boonInsightMult

baseInsight = floor(maxFloorReached × 15 + totalManaGathered / 500 + signedPacts.length × 150 + prestigeInsightBonus)
finalInsight = floor(baseInsight × mult)
```

**Note:** There is currently no specific victory condition or ×3 multiplier. These are awaiting design finalization.

### Prestige Upgrades (14 Types)

| ID | Name | Description | Max Level | Cost |
|----|------|-------------|-----------|------|
| `manaWell` | Mana Well | +500 starting max mana | 5 | 500 |
| `manaFlow` | Mana Flow | +0.5 regen/sec permanently | 10 | 750 |

| `quickStart` | Quick Start | Start with 100 raw mana | 3 | 400 |
| `elemStart` | Elem. Start | Start with 5 of each unlocked element | 3 | 800 |
| `unlockedManaTypeCapacity` | Mana Type Capacity | +10 capacity for selected mana type | 5 | 1000 |
| `pactBinding` | Pact Binding | +1 pact slot per level | 5 | 2000 |

### Pact Persistence
- Signed pacts do **NOT** persist through prestige — the player must re-defeat Guardians and re-sign pacts each loop.
- `pactSlots` starting value: 1 (upgradeable via `pactBinding` prestige upgrade)
- `pactSlots` starting value: 1 (upgradeable)

## Formulas & Calculations

### Damage Calculation (Complete)

```
baseDmg = spell.dmg + disciplineBaseDmgBonus
pctMult = 1 + disciplineDmgMult
elemMasteryMult = 1 + (elementalMastery × 0.15)
guardianBaneMult = 1 + (guardianBane × 0.2)  [guardian floors only]
rawDmgMult = 1 + boonRawDamage / 100
elemDmgMult = 1 + boonElementalDamage / 100

damage = baseDmg × pctMult × elemMasteryMult × guardianBaneMult × rawDmgMult × elemDmgMult
damage *= getElementalBonus(spellElement, floorElement)

// Critical hit
critChance = disciplineCritChance + boonCritChance / 100
critDmgMult = 1.5 + boonCritDamage / 100
if (random() < critChance) damage *= critDmgMult

// Special modifiers
if (floorHP / floorMaxHP < 0.25) damage *= 2    // Executioner
if (rawMana < maxMana × 0.5) damage *= 1.5      // Berserker

// Armor reduction
effectiveArmor = max(0, enemyArmor - armorPierce)
damage *= (1 - effectiveArmor)

return floor(damage)
```

### DPS Calculation

```
dps = damage × castSpeed × attackSpeedMultiplier
```

### Elemental Bonus Lookup

```
getElementalBonus(spellElement, floorElement):
  if spell == floor: return 1.25 (same element)
  if spell opposes floor: return 1.50 (super effective)
  if floor opposes spell: return 0.75 (not very effective)
  return 1.00 (neutral)
```
