Room of Bright Moon: if you are a cleric (or any other class with a good Turn Undead), just drink an invisibility potion, activate Turn Undead and sit in one of the dark areas. Endless Shadows will keep on spawning in groups of 3 every 15 seconds or so, and die instantly. Easiest XP of the game (420XP for each Shadow). I just left it running for about 5 minutes, after which it seemed like a very cheap and silly way to get XP, and I reloaded.

It seems like a bug that should never have existed (still in with the latest patches of the Steam edition of BGII:EE as of the date of this post), because as far as I could tell, you can just leave it running and level up like there's no tomorrow.
