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 the bonus from Shadow Armor, for a maximum increase of +65%.

Note: This increases the speed of all melee items, including pickaxes, hammers and other tools. This accelerates mining, cutting wood, removing walls, and similar tasks, as well as the more obvious weapon bonus.
