Some models have 'Bound' spells, which may be contained within a magic item or given by a special rule, and which they can cast in the usual manner. If a 'Power Level' is given, this is added to the result of the Casting roll to give the casting result. If no Power Level is given, nothing is added – the result of the Casting roll is itself the casting result. When casting a Bound spell, there is no risk of a miscast or chance of a perfect invocation.
You may attempt to dispel a Bound spell as usual. Magic items that dispel or destroy spells work as normal against Bound spells. When dispelling a Bound spell, there is no risk of being outclassed in the art.
A model can only cast a single Bound spell per phase. Possessing a Bound spell does not make a model a Wizard.
