Create a fresh 1.16.5 profile in Curseforge (tested on both the latest Forge version and 36.2.20 where I remember it still worked)
Only install Epic Knights + dependencies, no other mods
In a new world, try using any weapons with a two-handed tag
Equip a shield/other item in the off-hand slot and repeat step 3
Observe that while there is red text saying the damage and attack speed should've dropped due to off-hand slot being occupied, in reality the damage and attack speed do not change and stay the same
Expected Behavior
Attack/speed reduced when the off-hand slot is occupied
Steps to Reproduce
Steps to reproduce:
