Some gameplay tips:

Chance Guards

Chance Guards is a pair of normal unique gloves that boosts magic finding and gold finding a lot. About 50% of magic finding characters and more than 80% gold finding characters use chance guards. Although it's very useful to hunt D2 items or gold, it's almost useless for combat only characters because its other bonuses are very limited.
