Pathfinder 2e Action / Feat: Signature Spell

Requirements Spellcasting

Description You’ve learned to cast some of your spells more flexibly.    
Applications For each spell level you have access to, choose one spell of that level to be a signature spell. You don’t need to learn heightened versions of signature spells separately; instead, you can heighten these spells freely. If you’ve learned a signature spell at a higher level than its minimum, you can also cast all its lower-level versions without learning those separately. If you swap out a signature spell, you can choose a replacement signature spell of the same spell level at which you learned the previous spell. You can also retrain specifically to change a signature spell to a different spell of that level without swapping any spells; this takes as much time as retraining a spell normally does.
