This mod performs entirely different functions depending on game version, due to changes within both Better Combat and Apotheosis. 

Please read below!

1.21.1:

Better Combat applies Entity Interaction Range modifiers to weapon Attack Range on 1.21.1+

On these versions, Apothic Combat fixes Better Combat's resolution and combination of entity interaction range modifiers in item tooltips, so that they work properly with Neoforge's "Merged Tooltips", and properly include/exclude modifiers from unexpected sources like curios, gems, or items you aren't holding. 

Apotheosis has also removed the "Heavy Weapon" category entirely, so one-handed and two-handed weapons now use the same affixes.

1.20.1:

Apotheosis and Better Combat have some conflicting features on 1.20.1 -- 

• Apotheosis adds a "Heavy Weapon" category, which is somewhat similar to the concept of Better Combat's two-handed weapons, but the two have no relationship at all.
• Apotheosis (and Forge) treat attack range as an entity attribute and allow growth with gems and affixes, but Better Combat prevents these from working as it defines attack range as an immutable weapon property defined with its own JSON format.

1.20.1 Features for this mod:

• Registers all two-handed Better Combat weapons automatically as HEAVY_WEAPON for Apotheosis
• Removes Entity Reach modifiers (and tooltips) from weapons, deferring entirely to Better Combat's Attack Range weapon property
