So I've been testing every older version of the mod and I've found that versions 5.0.5 and above have the animations of all weapons break when the latest version Wizard staff is installed. Versions 5.0.4 and below work fine. If both mods are in a modpack, the animations break regardless of what version EFM is in.

As for the suggestion, it would be nice to have an option for custom weapons for guns, one fore handguns and one for rifles. No need for extra animations I just want them to be held properly when using combat mode. I believe the loaded crossbow animation is already compatible with most rifle mods out there.

After the research, I found that the Wizard staff mod uses a different way of rendering holding items from vanilla. Since I don't have the authority to modify the Wizard staff's code, It couldn't be fixed.

And the guns are not supported by Vanilla Minecraft, Many gun mods have different mechanisms to shot a gun. Epic Fight can't recognize all those mechanisms to play the matching animation.
