Masters of Mutagens

When resolving an attack made with a poisoned weapon by a model with this obsession against a unit that is not a VEHICLE or TITANIC, an unmodified hit roll of 6 automatically scores a hit and successfully wounds the target (do not make a wound roll). This does not apply to Artefacts of Cruelty. For the purposes of this obsession, a poisoned weapon is any weapon with the Poisoned Weapon ability (see Codex: Drukhari).
