Venomancer

Venomancer is a rollable gear effect in Minecraft Dungeons II for players who fight dirty. 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. Poison-focused builds that wear enemies down with toxins and debuffs will find this one a natural fit.
The documented tier I value is 10%. 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 all gear effects, the rolled tier rises with threat level, and stronger versions drop on higher-threat gear.
Rarity limits effect slots: common gear rolls none, rare gear rolls one, and special gear 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. Stack Venomancer with fellow venom picks Tainted, Alchemist Effect, and Sorcerer for a build that poisons everything it touches.
