Items used to create brand new monsters with traits corresponding to the trait of the charm. They come in three varieties: lesser, true, and blank.

Lesser charms are only useful for specifying a trait a monster will have, rather than letting the trait be selected at random. Two can be created a month by a demon lord, if the demon lord has used a true charm of the same trait in the past. They are the most common charms.

True charms not only specify a trait that a monster will have, but also give that trait a power boost. The completed monster will have stronger abilities related to the corresponding charm trait. They are somewhat hard to get a hold of, but a demon lord can choose to create one a month instead of creating two lesser charms if the true charms trait is the same as the trait of the demon lord.

Blank charms are charms without a trait. When a demon lord uses them, they will be transformed into either a true or lesser charm with whatever trait the demon lord chooses. They are given out by the Grand Demon Lord once when a demon lord is first created, and once when a demon lord 'graduates' from the Grand Demon Lord's castle. There are no other known ways to get one.
