Cinquedea

The Cinquedea is a Pre-Hardmode non-consumable dagger sold by the Bandit for. When used, it automatically throws a dagger that is affected by gravity. The dagger can pierce one enemy.

Performing a stealth strike with the Cinquedea will cause the next dagger thrown to home in on nearby enemies after striking an enemy.
