it seems this mod share a incompatibility with weapon leveling, i created a profile to send the log, the only mods i used to test that was better combat, Idf and the mentioned Weapon leveling, honestly i feel the Rpg energy this mod combined makes it perfect for a RPG theme modpack.

here is the log :

thank you for all your hardwork

I'll look into it shortly; looks like a cool mod.

EDIT: There's nothing I can do from my end. Weapon Leveling is trying to mixin to a method I absolutely need to overwrite for IDF to work. You can ask the author of Weapon Leveling to try and find an alternate method. That would be the only way. The method is LivingEntity$actuallyHurt

alright, thanks for the info and thanks for taking your time to look into it, as always great work
