Moon Stone

The Moon Stone is a Hardmode accessory which has a 2.86% / (1/35 / ) chance to drop from Vampires during the Solar Eclipse event. It grants the same stat bonuses as the Sun Stone, but these bonuses will only activate during the night or during a Solar Eclipse.

The stat bonuses are:
 * +10% melee speed
 * +10% damage (all types)
 * +2% critical strike chance
 * +1 HP/s health regeneration
 * +4 defense
 * +15% mining speed
 * +0.5 minion knockback

Tips

 * The accessory may prove useful during the battles with the mechanical bosses, since these take place at night.
 * An easier/faster way to get the Moon Stone is by placing a Water Candle or consuming a Battle Potion because the Blood Moon and Solar Eclipse does not have a set spawn rate.

Trivia

 * The Moon Stone and its counterpart, the Sun Stone, could be a reference to the platform-adventure action role-playing game . There are two items with very similar names, looks, and effects in the game: Moonstone and Sunstone.
 * Futhermore, the main character of the game, Alucard, is a Dhampir, which are the product of a human parent, and a vampire parent, and the item is dropped by the Vampire enemy, which could reference Alucard's father, Dracula.
 * Despite the fact that this item is obtained from the Vampire enemy, its counterpart, the Sun Stone, is obtained from the Golem boss.
