Skill types, exclusive skills, and transmuters
Skills may be active, toggled, or passive; toggles reserve energy, only one exclusive skill can be active, and transmuters fundamentally alter a skill.
How it works
The compendium describes active skills as cast or toggled and passives as not cast. Toggled skills are usually activated once and reserve part of the Energy bar. Only one Exclusive skill may be active across all trees. Transmuters are one-to-three-point passive branches that fundamentally change how a skill works; its example adds a cooldown to Dreeg’s Evil Eye while adding damage and area of effect. The source also says higher-tier path abilities need not require every sequential ability.
