+### Equipment Stats (ItemStats)
+
+Weapons have per-type **attack bonuses** — these determine accuracy based on the weapon's `attack_type`:
+
+| Field | Description |
+|---|---|
+| `stab_attack` | Accuracy bonus for stab attacks |
+| `slash_attack` | Accuracy bonus for slash attacks |
+| `crush_attack` | Accuracy bonus for crush attacks |
+| `science_attack` | Accuracy bonus for science attacks |
+| `ranged_attack` | Accuracy bonus for ranged attacks |
+
+Armor has per-type **defense bonuses** — the mob's `attack_type` determines which defense is used:
+
+| Field | Description |
+|---|---|
+| `stab_defense` | Defense vs stab attacks |
+| `slash_defense` | Defense vs slash attacks |
+| `crush_defense` | Defense vs crush attacks |
+| `science_defense` | Defense vs science attacks (negative on metal armor) |
+| `ranged_defense` | Defense vs ranged attacks |
+
+Other damage/utility bonuses:
+
+| Field | Description |
+|---|---|
+| `strength_bonus` | Melee max hit bonus |
+| `ranged_strength` | Ranged max hit bonus (on ammo) |
+| `science_damage` | Science max hit bonus |
+| `technology_bonus` | Reduces tech battery drain rate |
+
+### Attack Type
+
+Weapons should always set `attack_type`. Common mappings:
+
+| Category | attack_type |
+|---|---|
+| Swords | slash |
+| Daggers | stab |
+| Axes | slash |
+| Pickaxes | stab |
+| Bows | ranged |
+| Unarmed | crush (default) |
+
+### Equipment Requirements
+
+Higher-tier equipment requires skill levels to equip:
+
+```yaml
+requirements:
+  attack: 20      # melee weapons
+  defense: 20     # armor
+  ranged: 30      # ranged weapons/armor
+```
+
+Standard tiers: bronze/iron (none), steel (5), black (10), mithril (20), adamant (30), rune (40), dragon (60).
+
+### Ranged Ammo
+
+Arrows and bolts use `ranged_strength` for damage. Accuracy comes from the bow:
+
+```yaml
+id: iron_arrow
+name: iron arrow
+stackable: true
+equip_slot: ammo
+stats:
+  ranged_strength: 10
 ```
