Seek yon large Treasure Chests and maybe you will see a colored box in your inventory. If so it means you have a Possessed Weapon. So you can bypass that large boss fight and drain on your health if you get lucky with a NPC or a large Treasure Chest. If you see the colored box and odd name- you can rename your Possessed Weapon and customize it. Dyann’s Focused Can of Whuppass, or Stiletto Breaker were a few of mine.
