# Enchanter Attunement — Design Spec

> Describes the Enchanter attunement: identity, unlock flow, mana behavior, full
> discipline list with stats/perks, systems unlocked, and attunement level interactions.

---

## 1. Objective

The Enchanter is the starting attunement and the gateway to the enchanting system.
It provides access to Transference-based disciplines that unlock enchantment
effects, boost enchantment power, and provide study/utility bonuses. The Enchanter
is always the first attunement a player uses, and it remains relevant throughout
all stages of the game through its 10 disciplines and the deep enchanting pipeline.

---

## 2. Identity

| Property | Value |
|---|---|
| **ID** | `enchanter` |
| **Slot** | `rightHand` |
| **Icon** | `✨` |
| **Color** | `#1ABC9C` (Teal) |
| **Primary Mana** | `transference` |
| **Raw Mana Regen** | +0.5/hour (base, scales with `1.5^(level-1)`) |
| **Conversion Rate** | 0.2 raw→transference/hour (base, scales with `1.5^(level-1)`) |
| **Unlock** | Starting attunement (unlocked by default) |
| **Capabilities** | `['enchanting']` |
| **Skill Categories** | `['enchant', 'effectResearch']` |

---

## 3. Unlock Condition and Flow

The Enchanter is **always unlocked** — it is present in the initial game state:

```typescript
attunements: {
  enchanter: { id: 'enchanter', active: true, level: 1, experience: 0 }
}
```

No unlock flow is required. The player begins the game with Enchanter active.

---

## 4. Raw Mana Regen Contribution

Base regen: **+0.5/hour** (at level 1). Scales exponentially:

```
effectiveRegen = 0.5 × 1.5^(level - 1)
```

| Level | Raw Regen |
|---|---|
| 1 | 0.500/hr |
| 5 | 2.531/hr |
| 10 | 19.221/hr |

---

## 5. Mana Conversion Behavior

The Enchanter is the **only attunement that converts raw mana to Transference**:

```
effectiveConversionRate = 0.2 × 1.5^(level - 1)
```

This is an automatic per-hour conversion. Each tick:
- `0.2 × 1.5^(level-1) × HOURS_PER_TICK` raw mana is consumed
- The same amount is added to the Transference mana pool

At level 10, the Enchanter converts **7.69 raw→transference/hour**.

---

## 7. Systems Unlocked

The Enchanter attunement gates the **Enchanting System** (see `enchanting-spec.md`):

- **Design** stage: Create named enchantment designs
- **Prepare** stage: Clear existing enchantments, ready equipment
- **Apply** stage: Apply saved designs to prepared equipment

---

## 8. Puzzle Room Behavior

In the spire, every 7th floor has a puzzle room. When the room type is
`enchanter_trial`, progress scales at 2.5–3% per tick per Enchanter level.

---

## 9. Attunement Level Interactions

Higher Enchanter level affects:

1. **Raw mana regen**: `0.5 × 1.5^(level-1)` per hour
2. **Transference conversion rate**: `0.2 × 1.5^(level-1)` per hour
3. **Enchanting XP → Attunement XP**: Enchanting awards Enchanter XP (1 per 10 capacity used), feeding back into leveling

Attunement level does **not** directly affect enchantment strength or discipline
power — those scale through discipline XP alone.

---

## 10. Discipline Dependency Chain
