It can also be quite good for grinding, if you have a few - say trinkets - you will be able to activate a new trinket for every mob. Should burn them down pretty fast.
Its because you cant swap items other than your weapons in combat that makes this pretty.. useless (cant find a better word).
Anyway, good tip! I bet not many at all know about this, including me.
