Incantation Definitions

The following terms are used extensively in this section of the chapter:

Incantation: Powerful ritual magic that requires successful Knowledge (arcane lore) checks to cast. Incantations don’t require spellcasting ability, don’t take up spell slots, can’t be improved using metamagic feats, and need not be prepared ahead of time.

Factor: An aspect of the incantation that’s built in when the incantation is designed. Casters have no control over factors; they’re an indelible part of the incantation. When a GM designs an incantation, factors are useful ways to customize an incantation.

Option: Aspects of the incantation that make it easier or harder, depending on choices the caster makes. Options provide modifiers to the caster’s Knowledge (arcane lore) check.

Seed: The building blocks of incantation, seeds describe magical effects in general terms.
