Better stock up on Enhancement scrolls.

Durability depends entirely on your attack speed. For a class using a hurricane like skill, it depletes rather quickly.

I guess that makes sense for a weapon, but I thought armor would lose durability either when you die or when you get hit. I'll have to mess around and see how cumbersome/expensive it is, and if these bonuses are worth the extra cost and hassle. I also wouldn't be terribly surprised if something gets added to prevent durability loss in one form or another, since it doesn't seem like a coincidence that these unique items have durability and that repair costs were lowered not too long ago.

I also hope that there's some way to add some of these effects to existing items at some point, but that one does seem a little farfetched; or it wouldn't be cheap anyway.
