Custom Abilities & Attacks

Custom abilities are runtime proven end to end in FTK2.ModAPI 0.5.9.

The accepted ExampleMod run proved this complete native path:

registration → activation → custom item reference → inventory tooltip
→ localization/presentation/icon → equipped weapon enumeration
→ combat enumeration/button → visible and selectable action
→ native execution → correlated enemy HP damage → clean shutdown

The tested community.example:flame_cleave action reduced its correlated target from 14 HP to 0. The session completed with 69 passes, 0 failures, and 0 errors; the full automated suite passes 599 / 599 checks.

What the public API supports

• namespaced CustomAbilityDefinition recipes;
• creation from compatible native FTK2 templates;
• typed targeting, row/tile rules, action flags, focus/ammo flags, animation identity, AI tendency, effects, and tags;
• native stat-change effects and references to existing FTK2 statuses;
• owner-scoped localization plus template presentation/icon reuse;
• item action references with per-item SkillRollData;
• native equipment, combat action, and execution integration.

New status definitions, passive definitions, animations, VFX, SFX, and arbitrary action-graph authoring are not implied. Reuse only the existing native resources and supported properties established by the chosen template.
