The Crumbling Hall part of One Step at a Time achievement is currently impossible to achieve because there’s 2 layers of runes on the floor slightly offset making it impossible to avoid getting hit by damage and knocked around.

The quest requires you to loot the item at the end of the room so you can’t utilize a friend doing the quest progress for you, and it’s currently not possible to get across the room without triggering any rune traps.
