Augment Protocol is an armor-gated augment system. The armor you wear (iron, diamond or netherite) sets how many passive, active and flex augment slots you get, and you fill them with craftable augment items on the Augments Gear screen.
Passives are always on. Actives fire on the I, J, K and L keys and are paid for with charge items, energy cells or cooldowns. A full netherite build unlocks one ultimate on the U key. Every player also gets a Data slot for information augments, a back slot for an elytra or other back gear, and four ammo slots for quivers and TaCZ ammo boxes.
The mod also adds Recall Pads, plasma weapons, energy ammo, quivers, a jetpack, a parachute and a grapple, and shows a build profile with augment pair synergies.
Requires Minecraft 1.20.1, Forge 47 or newer and Caelus API. TaCZ is optional. Install it on both the client and the server, with the same version on each.
