This mod adds in the "God Armor" originally added in Minecraft 1.14.2 to allow God Armor to be created in current and previous versions of the game. The datapack supports versions 1.14 and up.

Throw any piece of armor, any type and level of protection, and a single diamond on top of an anvil. If it does not already have that type of protection, it will apply the enchantment immediately. It will up the repair cost tag on the armor, so I would suggest doing it last so you don't run into the "Too Expensive" bug.

Simply copy and paste the zip file into your Minecraft save's datapack folder. By default the location is "C:\Users\[USER]\AppData\Roaming\.minecraft\saves\[WORLD]\datapacks"
