This is a checklist for the Dark Souls III Item Randomizer by thefifthmatt. It covers all key items, boss souls, estus shards, undead bone shards, ashes, crystal lizards, ring locations, and shop checks across the base game, Ashes of Ariandel, and The Ringed City.
Create a room to share progress with your co-op group in real time - just give everyone the same room code and checks will sync automatically.
