Copper Golems: Mend ’Em & Send ’Em

Damaged copper golems can be repaired by right-clicking them with copper ingots, and each ingot restores 3 HP, which is 25% or 12 max HP for a full golem. Waxed or oiled golems take the same treatment, and a golem at full health keeps the ingot in hand. Honeycomb works in two ways: the first one applied acts like vanilla wax, while later honeycomb stacks into up to five oil tiers. Each tier adds one level of Speed, so a golem can reach Speed V. The effect lasts about one real-world hour, or 72,000 ticks.

Oiled copper golems patrol and react to hostile mobs within a short radius, dealing 0.5 hearts of damage with a gnat-like melee swing that briefly slows the target. Creepers and players are ignored. The mod runs on the logical server, while the honey tint and the oil highlight are handled by the client. Vanilla chest sorting, oxidation transitions, poppy gifts and wax or axe interactions keep working. The mod needs Fabric API on Fabric Loader and is released under the MIT License, so it is open source. Installing it on the client alone covers single-player and the integrated server, and multiplayer needs the matching jar on the dedicated server. Files exist for 1.21.9 – 26.2.
