# Slots

A character wears fifteen items in thirteen slots. `hand` and `finger` hold two items each; every other slot holds one. This skill owns the slot order, the slot odds and the optional equipment bonus.

## Schema

```ts
type Slot = 'tool' | 'offhand' | 'head' | 'neck' | 'back' | 'shoulders' | 'chest' | 'waist' | 'legs' | 'feet' | 'wrist' | 'hand' | 'finger';

type SlotsResponse = {
  order: Slot[];                   // the canonical order: iterate equipment in it
  totalItems: 15;
  slots: Array<{ slot: Slot; capacity: 1 | 2; affects: string[]; setIndex: number }>;   // setIndex: the slot's gear table
};
```

```json
{
  "order": ["tool", "offhand", "head", "neck", "back", "shoulders", "chest", "waist", "legs", "feet", "wrist", "hand", "finger"],
  "totalItems": 15,
  "slots": [
    { "slot": "tool", "capacity": 1, "affects": ["physicalDamage", "magicalDamage", "attackSpeed"], "setIndex": 8 },
    { "slot": "offhand", "capacity": 1, "affects": ["physicalDamageReduction", "actionDamage"], "setIndex": 9 },
    { "slot": "head", "capacity": 1, "affects": ["maxHealth", "visionRange"], "setIndex": 5 },
    { "slot": "neck", "capacity": 1, "affects": ["ailmentResistance", "magicalDamageReduction"], "setIndex": 7 },
    { "slot": "back", "capacity": 1, "affects": ["physicalDamageReduction", "carryCapacity"], "setIndex": 15 },
    { "slot": "shoulders", "capacity": 1, "affects": ["carryCapacity", "maxHealth"], "setIndex": 6 },
    { "slot": "chest", "capacity": 1, "affects": ["maxHealth", "physicalDamageReduction"], "setIndex": 17 },
    { "slot": "waist", "capacity": 1, "affects": ["stamina", "carryCapacity"], "setIndex": 16 },
    { "slot": "legs", "capacity": 1, "affects": ["walkSpeed", "stamina"], "setIndex": 12 },
    { "slot": "feet", "capacity": 1, "affects": ["dodgeRate", "jumpHeight"], "setIndex": 13 },
    { "slot": "wrist", "capacity": 1, "affects": ["attackSpeed", "castSpeed"], "setIndex": 10 },
    { "slot": "hand", "capacity": 2, "affects": ["physicalDamage", "actionDamage"], "setIndex": 11 },
    { "slot": "finger", "capacity": 2, "affects": ["criticalHitChance", "ailmentResistance"], "setIndex": 14 }
  ]
}
```

That is the complete response. In CSV, `affects` is one cell with the names separated by spaces.

## Each slot

| Slot | Base types | Odds on one item roll | Material table |
| --- | ---: | ---: | --- |
| `tool` (the mainhand) | 145 | 17.93% | tools |
| `offhand` | 144 | 17.93% | tools |
| `head` | 20 | 9.50% | wearables |
| `neck` | 8 | 0.65% | wearables |
| `back` | 5 | 1.94% | wearables |
| `shoulders` | 8 | 9.50% | wearables |
| `chest` | 26 | 9.50% | wearables |
| `waist` | 4 | 9.50% | wearables |
| `legs` | 10 | 9.50% | wearables |
| `feet` | 5 | 9.50% | wearables |
| `wrist` | 13 | 1.94% | wearables |
| `hand` | 6 | 1.94% | wearables |
| `finger` | 7 | 0.65% | wearables |

A character or set roll keeps drawing until every slot is full, so those always have all 15. The base types of a slot are the entries of its gear table, `/api/tables/<slot>` ([Item properties](https://set.world/skills/item-properties)); the mainhand's base type decides the class ([Classes](https://set.world/skills/character-classes)).

## The equipment object

`equipment` in `/api/roll/character` and `/api/roll/set` is keyed by slot. `hand` and `finger` are arrays of two items; the rest are single items. The type and a filled example are in [Rolling an item](https://set.world/skills/rolling-an-item) and [Rolling a character](https://set.world/skills/rolling-a-character).

```js
const SLOT_ORDER = ['tool', 'offhand', 'head', 'neck', 'back', 'shoulders', 'chest', 'waist', 'legs', 'feet', 'wrist', 'hand', 'finger'];
const items = SLOT_ORDER.flatMap((slot) => [character.equipment[slot]].flat());   // 15 items
```

`equipmentOrbBreakdown` (characters) and `orbBreakdown` (sets) give the same walk ready-made: one `{ slot, affects, items }` row per slot.

## What `affects` means

It is a theme, not a modifier. Set never ships resolved item effects: `affects` names the attributes an item in that slot would naturally touch. What an item actually does is your rule.

## The optional equipment bonus

Off by default. With `equipmentBonus=1` on `/api/roll/character`, each equipped item adds points to one base stat by its grade, clamped at 24, and `finalStats` includes them.

| Item grade | Points per item |
| --- | ---: |
| F | 0 |
| E | 0 |
| D | 0 |
| C | 1 |
| B | 1 |
| A | 2 |
| S | 3 |

| Slots | Stat that receives the points |
| --- | --- |
| tool, hand | strength |
| offhand, feet | dexterity |
| head | intelligence |
| neck | wisdom |
| back, legs | agility |
| chest, waist | vitality |
| wrist | perception |
| shoulders | resolve |
| finger | luck |

Both hand items and both finger items count. The response reports the points as `equipmentBonuses`.

## A schema for your loadout

```ts
type Loadout = {
  characterId: string;
  slots: Record<Exclude<Slot, 'hand' | 'finger'>, string | null> & { hand: [string | null, string | null]; finger: [string | null, string | null] };   // your InventoryItem IDs
};
```
