Armamentarium
by gqstavo
Armamentarium adds more than forty weapons with passive and active abilities, and obtaining them depends on a severing mechanic that drops whetstones from specific mobs.
What it does
Weapons in Armamentarium are gated behind gear-based achievement progression. The first goal is crafting a Shotel Severance, which a Wandering Trader sells, and that purchase makes several basic whetstones available. Whetstones drop from specific mobs when they are killed under specific conditions with a matching weapon, so each weapon line has its own path to obtain.
Advanced whetstones cover the later tiers. An Angel-Stripped Whetstone comes from severing a Vex at Y 250, a Thunder-Charged Whetstone from a Creeper struck by lightning, and a Guardian-Spiked Whetstone after three Guardians are killed in quick succession. Greatalloy, a gold and black alloy found underground at about the frequency of diamond, supports the late-game crafting, and the mod's advancement page lists how to sever the rest.
Installation needs no other mod. Armamentarium runs on client and server, so the server and every player need it. Files are published for Forge and NeoForge, for 1.20.1 and 1.21.1, under the MIT License, which is not open source.
Key features
Forty weapons with abilities
Over forty weapons carry passive or active abilities that change how each one is fought with.
Severing drops
Whetstones drop from mobs killed under set conditions, so weapons are earned through play rather than crafted at once.
Advanced whetstones
Later whetstones require end-specific materials and are balanced against the vanilla endgame.
Legendary Trinity
The final tier of armaments is a set of three weapons tied to bosses, each with a distinct theme and playstyle.
