Cascading Ray
Feat 10
Source Pathfinder Impossible Magic
Prerequisites Spellstrike
Requirements Your last action was a successful Spellstrike, and the spell you cast dealt energy damage (acid, cold, electricity, fire, force, sonic, vitality, or void).
Magical energy spills out to extend beyond the creature you struck. The flowing energy forms a ray with a range of 120 feet originating from the creature you damaged. You can't target any of the creatures you damaged with your Spellstrike with the ray. Make a spell attack against the new target's AC, at the same multiple attack penalty as the Strike. On a hit, the target of the ray takes 1d4 damage per spell rank of the spell you used for Spellstrike, or 1d8 damage per rank if you cast the spell from a spell slot. The ray uses the same damage type as the spell dealt (choose one if it dealt more than one type of damage). This ray has the attack trait, the tradition trait of the original spell, and the trait matching the damage type.
