Tainted

Tainted is a rollable gear effect in Minecraft Dungeons II with a corruption-themed edge. It appears as a bonus on weapons, armor, and artifacts, and comes from the gear-roll system rather than the book-based Minecraft Dungeons II Enchanting Guide system. Players running poison, decay, or otherwise nasty builds will find this one's theme matches their toolkit.
The documented tier I value is 40% — a hefty starting point that makes even the lowest roll worth keeping. Higher-tier figures were not captured in the available data, so the exact scaling at tiers II and III is not listed here — but like every gear effect, the rolled tier rises with threat level, and stronger versions appear on higher-threat gear.
Rarity decides how many effects gear carries: common rolls none, rare rolls one, and special rolls two. The rolled tier tracks threat level — always tier I below threat 3, tier III possible from threat 6, and tier III as likely as tier II at threat 15. Combine Tainted with Venomancer, Alchemist Effect, and the corruption-adjacent Soul Cursed for a build that spreads misery wherever it goes.
