1st Monthiversary, or more commonly known as Monthiversary or Monthy, is a custom ExperienceRO charm that enables it's bearer to deal more damage by providing +10% damage to all races (Doesn't stack with Turtle General, etc.). It is character bound, meaning that it cannot be sold, traded with other characters, nor can it be put into inventory. It is unstackable, which in this case, means you cannot have more than one.
