Golemancy System — Design Spec

Describes the Fabricator attunement's combat system: golem types, loadout configuration, summoning lifecycle, maintenance costs, room duration, combat behavior, and discipline interactions.

⚠ Spec-defined, implementation pending. This spec is based on docs/specs/spire-combat-spec.md §9 and represents the intended design. The current code has golem data defined but disconnected from the combat pipeline.

---

1. Objective

Golemancy is the Fabricator attunement's combat contribution. The player configures a golem loadout outside the spire, then golems are automatically summoned at each room entry, fight alongside the player, and disappear after a fixed number of rooms or if their maintenance cost cannot be met.

Design goals:

• Golems provide parallel combat damage independent of the player's spells
• Different golem types offer tactical variety (single-target, AoE, fast, tanky)
• Maintenance cost and room duration create resource management decisions
• Hybrid golems require dual-attunement investment (Enchanter 5 + Fabricator 5)
• Golem loadout configuration outside spire allows strategic planning

---

2. Golem Slot Formula

Golem slots come from two sources that add together:

2.1 From Attunement Level

attunementSlots = floor(fabricatorLevel / 2)

Fabricator Level	Slots
1	0
2–3	1
4–5	2
6–7	3
8–9	4
10	5

2.2 From Discipline

The Golem Crafting discipline provides:

• Base golemCapacity: +2
• Perk golem-2 (capped, threshold 500, maxTier 2): +1 per tier = up to +2

Maximum total golem slots: 5 (attunement) + 2 (discipline) = 7

Note: The AGENTS.md states floor(fabricatorLevel / 2) with max 5 at level 10. The discipline-based capacity is additive on top of this.

---

3. Golem Loadout Configuration

The player configures a golem loadout from the Golemancy tab before entering the spire. The loadout defines which golems to attempt to summon and in what order. This configuration persists across rooms but not across spire runs.

The loadout is a prioritized list of golem IDs. On each room entry, the system iterates the loadout in order, attempting to summon each golem.

5. Summoning on Room Entry

When the player enters a new combat room:

onRoomEntry():
  for each golem in golemLoadout:
    if player has enough mana of golem.summonCostType >= golem.summonCost:
      deductMana(golem.summonCost, golem.summonCostType)
      activeGolems.push({
        ...golemDef,
        roomsRemaining: golemDef.maxRoomDuration,
        attackProgress: 0,
      })
      activityLog("${golem.name} summoned")
    else:
      activityLog("Not enough mana to summon ${golem.name} — skipped")

Key rules:

• Golems that cannot be summoned (insufficient mana) are not re-attempted within the same room
• Failed golems will be attempted again on the next room entry
• Summoning order follows the loadout priority list

---

6. Golem Combat

Each active golem attacks on its own attackProgress timer, identical to swords:

golemProgress += HOURS_PER_TICK × golem.attackSpeed
while golemProgress >= 1:
  dmg = golem.baseDamage
  if golem.element:
    dmg ×= getElementalBonus(golem.element, enemy.element)
  applyGolemEffects(golem, dmg, enemy)
  applyDamageToRoom(dmg)
  golemProgress -= 1

Key rules:

• Golems ignore Executioner and Berserker discipline specials
• AoE golems distribute damage across multiple targets
• Elemental matchup applies if the golem has an element

---

7. Maintenance Cost

Each tick, each active golem checks its maintenance cost:

tickGolemMaintenance(golem):
  if player mana[golem.maintenanceCostType] >= golem.maintenanceCost × HOURS_PER_TICK:
    deductMana(golem.maintenanceCost × HOURS_PER_TICK, golem.maintenanceCostType)
  else:
    dismiss(golem)
    activityLog("${golem.name} dismissed — insufficient ${golem.maintenanceCostType} mana")

Key rules:

• A dismissed golem is not re-summoned mid-room
• It will be re-attempted on the next room entry if mana has recovered
• Maintenance is checked every tick, not just on room transitions

---

8. Room Duration Limit

onRoomCleared():
  for each activeGolem:
    activeGolem.roomsRemaining -= 1
    if activeGolem.roomsRemaining <= 0:
      dismiss(golem)
      activityLog("${golem.name} has faded after ${maxRoomDuration} rooms")

Key rules:

• Room duration ticks down on room clear, not on room entry
• Golems persist through the full room they were summoned in
• When roomsRemaining reaches 0, the golem is dismissed

---

9. Golem Data Shape

interface GolemDefinition {
  id: string;
  name: string;
  tier: number;                    // 1–4 (determines general power)
  baseDamage: number;
  attackSpeed: number;             // attacks per in-game hour
  element?: ElementType;           // optional elemental type for matchup
  maxRoomDuration: number;         // rooms before disappearing
  summonCost: number;
  summonCostType: ElementType | 'raw';
  maintenanceCost: number;         // per in-game hour
  maintenanceCostType: ElementType | 'raw';
  onHitEffect?: GolemHitEffect;    // DoT, AoE, etc.
  armorPierce?: number;            // 0-1, bypasses this fraction of enemy armor
  aoe?: boolean;
  aoeTargets?: number;
}

---

10. Discipline Interactions

10.1 Golem Crafting Discipline

Perk	Effect
golem-1 (once @ 200 XP)	Unlocks golem summoning ability
golem-2 (capped @ 500, maxTier 2)	+1 Golem Capacity per tier (max +2)

10.2 Fabricator Level

Directly determines base golem slots: floor(fabricatorLevel / 2).

10.3 Dual Attunement Requirement

All 6 hybrid golems require Enchanter 5 + Fabricator 5. This means the player must have both attunements active and leveled to at least 5 to access the most powerful golem types.

11. Known Gaps / Implementation Status

Feature	Status
Golem data definitions	✅ Complete (10 golems in data/golems/)
Golem loadout UI	✅ Partial (GolemancyTab exists)
Summoning on room entry	❌ Not wired into combat tick
Maintenance cost per tick	❌ Not wired into combat tick
Room duration tracking	❌ Not wired into room clear
Golem combat (attack timer)	❌ Not wired into combat tick
Golemancy combat pipeline	❌ golem-combat-actions.ts exists but disconnected

---

12. Acceptance Criteria

#	Criterion
AC-1	Golem slots = floor(fabricatorLevel / 2) + discipline bonus.
AC-2	Golems are summoned on room entry if mana allows; failed summons are skipped for that room.
AC-3	Each golem attacks on its own timer using its attackSpeed stat.
AC-4	Elemental matchup applies to golem attacks when the golem has an element.
AC-5	AoE golems distribute damage across aoeTargets enemies.
AC-6	Maintenance cost is deducted each tick; golems dismiss if cost cannot be met.
AC-7	Dismissed golems are not re-summoned mid-room.
AC-8	Room duration ticks down on room clear, not entry.
AC-9	Golems disappear after maxRoomDuration rooms.
AC-10	Hybrid golems require Enchanter 5 + Fabricator 5.
AC-11	Golem loadout is configured outside the spire and persists across rooms.
AC-12	Golem HP is display-only; golems don't take damage from enemies.
