I think the skill was, but since you can\'t open any doors, right now it\'s not very useful. Don\'t know if they made openable doors for new client. Anyway, eventually it will be useful to pick locks, so you\'d be able to open doors, and im guessing it could work for chests too, if there are chests at some point. Although Im wondering if there\'ll be restrictions as to what doors you can open, because if we ever have player\'s houses... I don\'t know, that\'s not gonna happen yet so well worry about that then, for now, don\'t waste your time training that skill (as there will be wipes every now and then during the development process of the game)
edit:
Didn\'t now about that Karyuu...
*get\'s poked by curiosity and is tempted to test skil when the mac client is ready*
