Spell Requisite

Hermetic spells of high complexity sometimes require a requisite, an additional Art beyond the two Arts of a standard Form-Technique-combination. Examples are a Rego requisite to deflect a harmful (side-) effect of a Creo spell from the caster, or a second Form for a transformation spell.

Requisites may or may not increase the complexity (and thus level) of a spell, depending on whether they enhance the effect.
