A question on Barrage

I know that you can't set the Damage Per Target field on Barrage to 0, but can it be set to negative values safely? I wouldn't mind a Multishot that deals less than the hero's attack, not more. If not, then that's fine, but I'd like to know just in case.

I'm just curious, but does that field actually do anything?

You know, I'm not entirely sure. But I'm pretty sure it's what makes Barrage deal damage.

I don't think it does. I had a tower dealing 100 damage, but damage dealt was set to 25, but it always dealt 100 damage.

Strange. We'll have to see what other people say.
