Companion Guild Skill Lines
Companions in The Elder Scrolls Online can use Guild Skills from the Fighters Guild, Mages Guild and Undaunted Guild. These skills are slightly different from normal Guild Skills that players have access to in ESO and can be a useful way to customize the Companion’s combat style.

Companion Rotations: Priority and Cooldown System
Companions utilize a “Priority and Cooldown” system for combat. This works by giving every companion ability a cooldown of several seconds. Companions then can cast each ability as it comes off cooldown according to the skill order assigned on the companion skill bar. The Companion will attempt to cast each skill in order from the first ability to the last, then reset once all the cooldowns have expired.
