Flow of Elements (Teamwork)Source Inner Sea Races pg. 206
You can spontaneously channel your ally’s elemental essence, be it burning fire, freezing ice, crackling lightning, or searing acid.
Prerequisites: Ability to cast spells; ifrit, oread, sylph, or undine.
Benefit: Whenever you’re adjacent to an ifrit, oread, sylph, or undine ally who also has this feat, you can spontaneously replace or split a spell’s damage when casting it, as though the spell were affected by Elemental SpellAPG (without using a higher-level spell slot). The type of energy damage depends on your ally’s race: acid for oread, electricity for sylph, fire for ifrit, or cold for undine.
