I remember something a while back that addressed "Keys" in the game and what the grades were and so on... like the percentage that you were likely to get attacked on. Seems like they ALL attack me, and it is annoying.
Not all treasure chests are what they seem, there are actually 2 mobs, treasure chests and treasure boxes. The chests are mobs that attack, the boxes are the ones that give you goodies.
U used to be able to tell them apart by their label, but thats been patched, so now all of them are labelled "treasure chest" now. Sux eh .. thats why u should reveal too much on the boards :P
