EFM Extended
by deus_robson
EFM Extended is a Forge addon for Epic Fight that lets datapack authors define new weapon types, dodge skills and block traits without writing Java code.
What it does
The mod is meant for datapack creators who want to add features that the default Epic Fight Mod lacks. Its bundled example is a single patched iron longsword, included for testing, and the project documentation walks through how to build a datapack that extends the default setup. Epic Fight must be installed alongside EFM Extended, and the two together are published for Forge only.
New weapon types are defined in a weapon patch JSON file. A datapack can set heavy attack motions and animations, a push motion that plays when a weapon attack or block lands with greater knockback, and the stamina cost of that push. The patch also controls the active dodge skill, which occupies a skill slot, appears in the hotbar and is limited by a maximum number of dodges and a cooldown. A new Block Resistance attribute lets weapons block more effectively, and a weapon can be set to consume less stamina while blocking.
Six release versions are published, with the latest Forge file being 1.1 for 1.20.6, dated 2026-05-28. The mod runs on the client and on the server, so both sides need it. The code is public, but the project is released under All rights reserved and is not open source.
Key features
Datapack weapon types
Weapon types are defined through datapacks, so new weapon behaviour does not require changes to the mod's Java code.
Heavy attacks and push motions
A weapon type can set heavy attack motions and a push motion with its own animation and greater knockback.
Active dodge skill
A dodge skill fills its own skill slot, shows in the hotbar, and sets a maximum number of dodges and a cooldown.
Block Resistance attribute
Weapons gain a Block Resistance attribute, and a patch can lower the stamina a weapon uses while blocking.
