Magic Items

Spell Catalysts

Source Secrets of Magic pg. 168 1.1
The divergent magical practices of Golarion mean there's no one way to cast a spell. Whether out of competitiveness or a desire to personalize their spellwork, many magic users have added or substituted material components beyond the conventional.
Items with the catalyst trait are consumable material spell components that alter or magnify specific spells. Activating a catalyst is part of Casting the Spell. The catalyst might increase the number of actions required to Cast the Spell, as indicated in the catalyst's Activate entry. Additionally, the spell gains material components if it didn't have them already or adds the catalyst to its existing components. Because the catalyst becomes part of the material components, you can draw the catalyst as part of Casting the Spell.
