Moon Charm

The Moon Charm is a Hardmode accessory that, when equipped during night time, turns the player into a werewolf, and applies the Werewolf buff. The item is a rare drop from the Werewolf enemy. The resulting werewolf looks slightly different in color than the enemy. Players with this item equipped during a full moon can still be attacked by other Werewolves.

The buff provides these bonuses:
 * +2% Melee critical hit chance
 * +5.1% Melee damage
 * +5.1% Melee speed
 * +5% Movement speed
 * +3 Defense
 * Slightly increased jump height and jump speed
 * +0.5 HP regeneration per second (Like the Band of Regeneration)

Tips

 * The Moon Charm is a reasonably good accessory for melee fighters. Non-melee characters shouldn't bother with it, though Mages and Rangers interested in the effects of the Neptune's Shell might consider using a Celestial Shell (which combines the effects of the Moon Charm with the Merfolk transformation, and grants the Celestial Stone benefits) or a Moon Shell instead (which combines the effects of the Moon Charm with the Merfolk transformation, without the Celestial Stone benefits) if they want the aesthetics that come from the charm while gaining some level of usefulness from it.
 * The Moon Charm is very useful when fighting bosses as most bosses can only be summoned during the night. This means that you gain all the benefits of the accessory throughout the entire fight.
