if your actually playing, if wearing a luck suit cuases you to kill substantially slower the luck suit is not worth it.
All you need to do is equip the luck suit right before the moment of death.
99% of the time I'm fighting in my standard gear and only put on the luck suit at the very last moment before the coup de grâce.
Someone here on Stratics referred to the luck suit as having to put on a hard hat (workers suit) I'm starting to agree with them. Part of me wishes there was no luck in UO, and that I didn't have to carry around another suit.
Unfortunately, a luck suit has become mandatory if you want a shot at decent items.
