ItemsAdder doesn’t upgrade armor automatically like vanilla netherite. You need to handle the upgrade logic yourself.
The usual solution is to create a separate netherite version of the set and then define how players upgrade it

• Use a custom smithing recipe (leather set + netherite ingot → netherite set)
• Or handle it with another plugin (Skript, MythicMobs, Denizen, etc.)

ItemsAdder is only responsible for the items themselves, not the upgrade process.
So the workflow is:

• Leather set = one custom item set
• Netherite set = another custom item set
• Upgrade = recipe or plugin logic

That’s the cleanest and most common approach.
