The maleraunt Santin-Margorn created this iron colored mold. It has similar immunities as the russet mold. The spores of the metallis mold have an area of effect of 15' radius. They cause damage as a russet mold and corrode all metals (Reflex DC25). The destruction of the mold leaves a fine powdery substance which can be used for hurling at armored enemies, sprinkling on locks, hinges, and so on. This dead form of the mold only affects metals. The cloud of metallic gas lasts for 3-12 rounds.

In the Year 1542, spies working for Irastâmâz, snuck into Tâchumâz's dreaded Bloodtusk Fungal Labs, stealing the formula for making metallis mold.
