Moon Stone

The Moon Stone is an accessory that rarely drops from Vampires during a Solar Eclipse, a Hardmode-only event.

It grants the same stats as Sun Stone, however only during the night:
 * +10% all damage.
 * +2% critical strike chance with all attacks.
 * +4 defense.

Trivia

 * Possibly a reference to the Moon Stone in Castlevania: Symphony of the Night.
