Diamond Upgrade Template
Diamond Upgrade Template gives villagers a new trade that turns iron equipment into diamond, available from Armorer villagers at Journeyman level.
What it does
The mod adds a Diamond Upgrade Template, an item that lets players upgrade iron tools and armour to diamond. The template is offered by the Armorer villager profession, and only once the villager has reached Journeyman level. The trade costs 17 emeralds and one Diamond Upgrade Template, and no other source of the template is provided, so the trade is the only way to obtain it.
Because the upgrade depends on a villager trade, players who want diamond equipment early must find an Armorer and raise its level first. The mod runs on Fabric and Forge, and the environment is client and server, so both the server and every player need it installed. Builds cover 1.20.1 – 1.21.11 across five release versions, and the mod is released under All rights reserved, so it is not open source.
