Bardic Inspiration
Fully equip a Bard with instruments

Final Form

Fashionista
Unlock all alternative outfits

The Forgotten World DLC introduced 1 new outfit (Dungeon Explorer). It is located in the same room as the Stronghold Dungeon Blob Lock (on the top left corner hidden in the shadows). You will need to activate an ice orb to open the gate to the outfit. (credit: u/CptPhnx)
