Cast

Description

Cast is an Aura mechanic similar to Skill in that it executes a skill, however Cast instead "casts" the skill similar to how you'd expect an RPG hero or monster to do so. Cast will execute the given skill if the cast completes successfully (e.g. if the aura finishes normally), but can be interrupted.

Only one spell can be cast at a time, and which runs as an aura on the caster named #casting. Removing the aura from the entity will interrupt the cast. Any aura settings that cause the cast to stop early will also interrupt casting, such as cancelling on move or teleport.
