SULFUR PRIME — Every Time I Kill It, AI Makes It Stronger

The harmless little sulfur cube… patched into a six-stage adaptive boss. Here’s the experiment: I fought it, I won, and after every kill I sent my real battle report to Claude AI — which designed and coded a counter to my exact strategy. Six rounds later, this mod is the result. Every ability exists because a human tactic worked once and was never allowed to work again.

Requirements

Minecraft 26.2 (Java Edition)
Fabric Loader 0.19.3+ and Fabric API
Java 25+

How to play

Drop the jar in mods/, open a world with cheats, then:

/cube spawn <1–6> — summon any version at your crosshair
/cube stage <n> — evolve a living boss mid-fight
/cube demo <ability> — force a single ability cast
/cube info, /cube invuln, /cube reset, /cube reload

Every number (HP, damage, cooldowns, loot) lives in config/sulfurprime/stages.json — tune it and /cube reload applies live.

The six rounds

v1 AWAKENED — it learned to hunt
v2 MAGMA CORE — running away became a mistake
v3 OBSIDIAN CORE — shields stopped mattering
v4 AMETHYST CORE — your own arrows turned traitor
v5 BLUE ICE CORE — heavy blows started backfiring
v6 THE PRIME — everything at once… and two surprises I won’t spoil here

Each stage drops loot that funds your preparation for the next — beat the finale and crack open the jackpot vault.

Round 7 is your problem now
