A caster monster spell can be a spell used by a character class, a spell only used on scrolls or staves, or a custom-made spell for that monster. They include offensive and defensive spells.

* Offensive spells include effects such as a Firebolt, Fireball, Frost Nova or general player [[debuff]]s.

* Defensive spells are usually [[buff]]s, [[heal]]ing or [[resurrect]]ion spells.
