# RPG Engine — Remaining Work

## Missing Foundational Components

### `Faction` / `Relationship` (`components/faction.ts`)
Reputation score per faction ID. Drives dialog availability, shop access, hostile
aggro thresholds, and quest unlock conditions. A separate world-level faction
definition registry (neutral/friendly/hostile thresholds) pairs with this.

## Missing Systems

### `CombatSystem` (`systems/combatSystem.ts`)
Resolves attack attempts between entities. Needs a lightweight `Attack` marker
component (attacker entity ID, target entity ID, damage, damage type) that is added
to an entity to queue an attack for the next tick. Each tick the system:
1. Processes queued `Attack` components.
2. Applies damage to the target's `Health` stat (accounting for any defense modifier
   Effects on the target).
3. Removes the `Attack` component after resolution.
4. Emits `'hit'` / `'kill'` events on the target entity as appropriate.

Keeping the attack as a component (rather than a direct method call) lets other
systems react before resolution (parry window, shield-block effects, etc.).
