Moon Charm

The Moon Charm is an accessory, which when equipped on a full moon, turns the wearer into a werewolf (and applies the respective buff). It can be dropped by the Werewolf mob.

During a full moon, the buff provides these bonuses:
 * +1% melee critical hit chance
 * +5% melee damage
 * +5% melee speed
 * +5% movement speed
 * +1 defense
 * Slightly increased jump height and jump speed

It is a reasonably good accessory for melee fighters and certainly worth equipping during a full moon. Non-melee characters shouldn't bother with it, and it's not powerful enough to be worth waiting for a full moon before starting a difficult boss fight.
