Lucky Coin

This accessory is dropped from Pirates in a Pirate Invasion.

Extra coins have a (20%) chance of dropping every time you hit an enemy with melee, ranged, magic or summon attacks. Damage return effects like with Turtle armor and Thorns Potion won't drop extra coins, nor will hitting background animals like bunnies. From the 20% chance, there's a 89.1% chamce it will be copper coins, 9,9% - silver coins, 1% - gold cois. Every time it drops between 1 and 10 coins.

A good way to take advantage of this is with the Slime Staff. Against stronger enemies, the baby slime summoned by the staff will attack rapidly, but only do 1 damage per hit. This gives more chances for coins to drop.
