Moon Charm

The Moon Charm is a Hardmode accessory that, when equipped during nighttime, turns the player into a werewolf, and applies the Werewolf buff. The item is dropped from the Werewolf enemy with a chance of. Although the enemy is colored blue, the player Werewolf will be colored brown. 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 (similar to the Band of Regeneration, but with half the speed)

Tips

 * The Moon Charm is a reasonably good accessory for melee fighters. Non-melee characters should not 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 boss fights can only take place at night. This means that the player gains all the benefits of the accessory throughout the entire fight.
 * If a Blood Moon and Full Moon occur on the same time farming for the charm becomes much easier due to the massively increased spawnrates of enemies.
 * One can force this by using a Bloody Tear on a Full Moon.
