Chainmail under Armor
by NeykShon
Chainmail Under Armor lets a player wear a chainmail piece beneath the main armor in each slot, adding a layer of protection.
What it does
Chainmail is an additional equipment layer in each armor slot. The first chainmail piece goes into a slot, and a regular armor piece is then worn on top of it. Chainmail cannot be stacked with another chainmail piece in the same slot, which keeps identical pieces from being duplicated. To remove the chainmail, a player must first take off the armor worn over it.
Chainmail worn underneath the main armor reduces the damage that passes through to the outer layer. More chainmail pieces give stronger protection, and the percentages stack with the number of pieces equipped. A full set provides 19 percent damage reduction, made of 4 percent, 8 percent, 5 percent and 2 percent. The mod works on client and server, so both the server and every player need it. It requires Fabric API and is published only for Fabric, for 26.1.1 and 26.1.2, with 0.7b for 26.1.2 as the latest file. Released under the MIT License, it is open source.
Key features
Chainmail as an inner layer
Chainmail is placed under the main armor piece in each slot and absorbs part of the damage before the outer layer.
Stacking protection
Each equipped chainmail piece adds to the reduction, so a full set gives the largest share of protection.
Single piece per slot
Only one chainmail piece fits in a slot, preventing identical pieces from being worn in a stack.
Enchantment support
Chainmail supports enchantments, and enchantment effects interact between the inner and outer armor layers.
