Bow Supremacy's trick states:

**Multi-Shot (Bow Attack Trick)**: Using this trick fires 3 arrows

or bolts. If you hit by 4 or more, you inflict your ammunition’s

damage an additional time. If you hit by 10 or more, you inflict

your ammunition’s damage two additional times. In both cases,

roll separately each time you inflict damage.

My question is this:

Does this mean he fires 3 arrows, and does three times damage + 1 or 2 times more based on accuracy?

Or does it mean normal damage, and 1 or twice more damage based on accuracy?

The first option seems OP, the second makes more sense to me, but I'm looking for confirmation on it.
