GM and I were discussing how the trait Volatile Conduit from Ultimate Campaign (pg58) interacts with Call Lightning (CRB pg251).
As written...
Volatile Conduit:
Once per day as a free action, when you cast a spell that deals acid, cold, electricity, or fire damage, you can enhance that spell with volatile energy. When you do, it deals 1d4 points of extra damage of the same energy type.
Call Lightning:
Immediately upon completion of the spell, and once per round thereafter, you may call down a 5-foot-wide, 30-foot-long, vertical bolt of lightning that deals 3d6 points of electricity damage. The bolt of lightning flashes down in a vertical stroke at whatever target point you choose within the spell’s range (measured from your position at the time). Any creature in the target square or in the path of the bolt is affected.
We see four possibilities.
One. No interaction. The initial cast of Call Lightning does no damage, therefore they don't interact.
Two. The initial cast deals a bonus d4 damage, no additional bolts deal damage.
Three. On cast, you roll d4. All bolts gain damage equal to the result of that roll.
Four. You add d4 damage per bolt.
It is an evocation spell, and not a conjuration spell, so Call Lightning itself is dealing the damage, even if it isn't immediate. My assumption is that either 3 or 4 is correct, as it applies to the full spell.
