Yeah, like Polk said, it doesn't affect anything.

As it works, the chainsaw's multi-hits are just for cosmetics. Dev's changes made it so the amount of attacks don't matter for the final damage output and in fact, can be "less damaging" in case one of the attack rolls ends up missing or not a critical hit (which is why handguns suck).

What the Chainsaw has technically speaking is a higher chance to crit, since it rolls that many times, the critical flag for the attack is only 1. "Attack was critical hit", then it procs the on-crit effect once.

Which is intentional. A chainsaw sticks to someone then goes VRRRRRRRR. That's why it hits (or misses, or glancing) multiple times. If you stand still you take all of it, if you don't, it'll hit funny.

But I'm just being creative with the item's effects, if it's possible to make it so if the first attack hits, then it happens over several other attacks, it'd make this weapon both unique and really cool. (I.E, if you dodge the first hit, the attack stops and counts as a full miss without obeying the Gun Round rules).
