I might as well just start a list: Haemetic Phylactery might be a starting item if you have Alchemy I had a quest item which appeared as a wizard's sleeve. When I attempted to pick it up it changed to a blue lutefisk icon, keeping the same name. Drowning in Lava still uses that nice blue water drowning animation. Also: First. (maybe not but I've beaten at least 1 in 1000 players) Three related rather affecting bugs Monsters can sometimes move or attack after death. If they attack they don't do damage but still play the animation. You can still walk onto monsters if you move while they're moving. Monsters may hit you whlie you're moving off of a tile. I just died because an AI hit me going up the stairs in such a way that's not possible. They don't have extendable arms and can't move them forward, then turn right, then up the stairs to attack. That's not how it works.
