Feature description

When an item with DMC Loot modifiers is modified in the workbench it wipes away all of the attributes which means you can only use one or the other. The compatibility would be as simple as reading for the NBT Data that DMC loot adds and then transferring it over when you modify a weapon on the crafting bench. Considering that DMC Loot also works with armor it could also make a nice edition to the upcoming Tetra Armor update

How it improves the player experience

It allows players to use multiple mods instead of choosing one or the other. It could also create some really cool weapon and armor combos.

Tetra synergies

It synergizes with weapon customization and grants the player a chance to have an ENTIRELY unique weapon.

What does DMC stand for? Googling "DMC mod" turns up something else :P. I need to know how the data is stored. Could you run /data get entity @s SelectedItem with the item in your hand and either paste the console output or a screenshot here?
