## ⚠️ Implementation Notes

- All damage dice and stat values are **starting baselines**. Balance tuning is a human responsibility.
- Weapon/armor names may be reskinned for flavor (e.g., "TwinBee Aegis" instead of "Shield") but base mechanics must match this spec.
- Class proficiency restrictions from the main design doc apply here. An unproficient player may equip an item but incurs **-4 to attack rolls** and cannot add stat modifiers to damage.
- All gold (gp) costs map 1:1 to GogoBee **coins** unless the economy team decides otherwise.
- Item IDs follow the format: `wpn_<name>` for weapons, `arm_<name>` for armor.

## 10. Carry Weight (Optional Mechanic)

If inventory weight is implemented, use these rules:

- **Carry Capacity:** STR score × 15 lbs
- **Encumbered** (> STR × 5 lbs): -10 to movement speed (flavor; -1 to DEX rolls)
- **Heavily Encumbered** (> STR × 10 lbs): -20 to movement; disadvantage on STR/DEX/CON checks
- **Over capacity:** Cannot move. Combat actions at disadvantage.

Recommended: implement carry weight as a soft warning only in v1. Hard enforcement deferred to future patch.
