Hello, i have few questions about this mod's compatibility, i haven't tried it yet but it would be better to ask before doing so.

Is this mod compatible with Customizable Players? and what about the Resourcepack Fresh Animations? they're both great mods however they do not improve anything in the combat system like this mod does, i would like to know if compatibility is possible between these, since i as many others wish to combine these for an even better experience.

I apologize in advance if this troubles you in any way.
I'll be waiting for a reply, thank you!

Epic Fight uses an entirely different model from vanilla. They're designed based on vanilla models so it's technically incompatible.
