Every character has a basic attack skill and a Power Ability. In addition, each Eddie has a Special Ability which requires a full Fury meter in order to become available.
To increase the effectiveness of your skills, level them up with Skill Shards.
NOTE: Some skills are passive, meaning they're always in effect and do not need to be actioned. Passive skills will be displayed on-screen during battle.
