Feral Claws

Chests in Shrines in the Underground Jungle have a chance of containing this item.

Effects
Feral Claws increase your melee attack speed by 10%, and stack with one another as well as other attack speed bonuses.

With 5 equipped, there would be a 50% melee attack speed bonus, and when combined with a full set of Shadow Armor, would yield a grand total of a 65% melee attack speed bonus.
