Skills

The Game Mechanic Types of Skills describe the kind of Effect a skill applies to an Action, Action Type, Target, or Environment.
A single Skill may have multiple Types; the total count is capped by the Skill’s Rarity Rank.

Game Mechanic Types

  • Direct Effect — Immediate, one-resolution impact on an Action, Action Type, Environment, or Target (whether creature or object) with no persistence or special targeting/area rules (e.g., deal damage, heal, push/pull, move, create/destroy a simple object now).

  • Sense Effect — Reveals, filters, or masks information (identify, inspect, detect, highlight, track, ping, mark for UI). Produces knowledge, not alteration.

  • Alter Effect — Changes properties or resolution rules of actors or actions (convert damage/type, modify costs, tags, accuracy, resistances, immunities, caps, or calculations).

  • Proc Effect — Defines conditional or scheduled firing logic for other effects (on-hit, on-crit, on-move, after X actions, random roll, sequence/chain).

  • Extended Effect — Persists across Temporal Units; applies over time or while maintained (DoT/HoT, aura/channel, maintenance, lingering field).

  • Area Effect — Specifies spatial coverage independent of payload (cone, line, burst, zone, hazard template, terrain overlay).

  • State Effect — Applies, transforms, or clears statuses/flags on entities or systems (buff/debuff, cleanse/purge, silence/root, shield/ward, lock/unlock interactions, toggle dungeon/system flags).
