number
Ability ID of the current morph (specific rank). Used as a key into g_SkillsData and in GetEsoSkillDescription to get the correct description with the slotted morph's bonuses. If absent, the engine uses skillId (for morph-less skills).
skillId
number
Lookup key in g_EsoSkillActiveData — matches origSkillId in the Build Editor DOM (base/unmorphed skill ID). For morph-less skills it equals morphSkillId.
