Off the top of my head, I can only think of 3 skills that have passive cosmetic effects:
- (Daredevil) Distracting Daggers - 3 blue daggers rotate around the right wrist of the Daredevil.
- (Guardian) Signet of Courage - Blue disc on the floor below the Guardian.
- (Warrior) Signet of Rage - Orange orbs float upwards around the Warrior.
Are there any other skills that have effects like this when they are on your skill bar? Because they're pretty cool and I'd love more.
