  • Corrosive. Any non-magical metal weapon used to hit the Devil’s Fingers immediately corrodes with rust. Each time a weapon hits the fungus, after calculating damage, the weapon’s damage rolls are permanently given a -1 penalty. If this penalty drops to -5, the weapon becomes useless.


  • Grab. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d4+2) bludgeoning damage. The devil’s fingers can target metal armor or a metal shield, causing it to have a cumulative -1 penalty to the AC it offers with each hit. The fungus can also target a held metal weapon, causing it to rust as described under the Corrosive trait above.


The devil’s fingers are a subterranean species of fungi.

More commonly called the rust fungus, the devil’s fingers have long, reddish, serrated tendrils that appear like the pointed fingers of a hand. The fungi, but especially its hand and fingers, are coated in a corrosive goop.

When the fungus senses movement or ferrous metal, its hands extend outward (as far as 5 feet) and latch on tightly to its prey. The fungus possesses a ravenous appetite for ferrous metal and will prioritize the targeting of armored legs, shields, and weapons.
