That mod is meant to be used as a api for datapackers to create and implement some new interesting features that lacks on default EFM.
The default mod only have one patched weapon(the iron longsword) for test purposes.
First, go to https://epicfight-docs.readthedocs.io and learn how to create datapacks for the default EFM mod, then u can go to https://github.com/oksimvey/EFM-Extended/blob/master/tutorial.json and take a look at an example to learn how to create datapacks with this mod.
The current additional features are;
Heavy Motions;
Now when creating an new weapon type with datapacks, you can define heavy attack motions, that animations gonna be played when you hold click, just like Dark Souls and Elden Ring
Push Attack;
You can also define an "push" motion for the weapon type, that animation gonna be played if you attack while blocking, and have a greater knockback. You can also define how much stamina % the push gonna consume and the push impact in the weapon patch json file.
New Dodge Mechanics;
Now if you have an active dodge skill in your skill slot, you will have a new "limiter" based on your weapon, it gonna show on your hotbar how many max dodges you can have, and how many dodges are in cooldown, you can define the max dodges and doge cooldown for each weapon in the weapon patch json file.
New Guard Mechanics;
Now weapons have a new attribute called "Block Resistance", weapons with a higher block resistance gonna consume less stamina when blocking, you can also define this in the weapon patch.
