A Series of Unfortunate Rolls
Ring of Recall
Current owner: Medivh Alucard
Purchased from the pawn shop in Waterdeep for 600 gp just before leaving for the Phantom Limit (Act III, Ep 1).
Once per day, allows the spellcaster wearing it to regain a spell slot after having failed at casting a spell.
It’s no big deal… it happens to lots of wizards.
