Synergistic Spell Feat 20
Source Pathfinder Lost Omens: Character Guide
Prerequisites Halcyon Spellcasting Initiate, Fulminating Synergy, legendary in Arcana, legendary in Nature
You combine your synergy and spells into a fantastic web of magic, allowing you to cast two spells at once. If the next action you use is to Cast a Spell from one of your halcyon spell slots, after that spell resolves, you can Cast another Spell as a free action. This spell must be cast from one of your halcyon spell slots and be a spell that would normally take two actions to cast.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
ArchetypeThis feat belongs to an archetype.
MetamagicActions with the metamagic trait, usually from metamagic feats, tweak the properties of your spells. You must use a metamagic action directly before Casting the Spell you want to alter. If you use any action (including free actions and reactions) other than Cast a Spell directly after, you waste the benefits of the metamagic action. Any additional effects added by a metamagic action are part of the spell's effect, not of the metamagic action itself.
