Addition context: I was using a mod called Project: War Dance, this seems to have caused the OffHandCombat to throw the error.

War dance is a pretty stable mod and would work great with OffHandCombat.
The mod recreates vanillas combat system from the ground up adding a parry system and staggering.
Would love compatibly for it!

They could leave the attack speed game modifications unchanged, that was done correctly enough I believe.

This would be enough?

That is because that mod is overriding the offhand modifications I do to the game, as long as that happens the mods will be incompatible

The only solutions is either of us completely overrides interfering changes, and it's possible it'll start an arms race.

A solution I'd prefer (but might not happen) is they remove the offhand aspect of the mod, since what they do is also not entirely correct, and add this mod as an optional dependency.

They could leave the attack speed game modifications unchanged, that was done correctly enough I believe.

yeah

Yeah they just have to remove the offhand attack from their mod.

Why is it not quite correct? The original offhand attack function of PWD came from its predecessor, Taoism, so I know the current function is extremely hacky. I can remove it, but I'd like to know how I can improve for the future.

Oh no nvm, I assumed you were doing it the wrong way by copy pasting the attack logic for the offhand because you mention an offhand attack event, but you actually swap the items and apply the attributes like should be. You're good Sorry :<

I'd say just copy what I do in this mod add a incompatibility warning so people don't install this by mistake.

i-
so, huh?

ah oops, so Project:War Dance mod already adds off hand attacks, you don't need to install this mod
