How exactly does bonus work?

[OneShot17]

So I know that there's a way to make a weapon that, for example, had a bonus that every time it fired it added a shot. Or maybe increased shield piercing, or used more missiles. If that was possible, how would it work? And would it glitch the UI? Also, is it possible to add two or more bonuses to a single weapon? Again how would this work, and would the UI glitch? Thanks!

You're thinking of the chain power on weapons, coded with the <boost> tag. You can only apply one boost per weapon.....I think. (I may have to try that.)

Unfortunately, the only two boosts that exist so far are cooldown-drop and damage-boost. I don't know if you can increase the number of shots per chain, and I doubt you can (considering modding is about using existing objects, not making new ones).
