Rust Ooze

Creature 3 (uncommon) — mindless, ooze

Pre-Remaster content. May include legacy alignment.

AnvilSnareLANDAQUATICooze

Urban pollution breeds all kinds of new and interesting ooze creatures. These reddish-brown globs wriggle through sewers and other waterways in search of iron pipes, metal trash, and other objects that rust.

Offense

Melee Pseudopod (unarmed) +11, Damage 1d6+5 bludgeoning plus Rust, Tetanus

Abilities

Motion Sense 60 feet — A rust ooze can sense nearby creatures through vibration and air or water movement.
Corrode Weapon
Metal Resistance — A rust ooze has resistance 5 to metal weapons.
Rust — When a rust ooze critically succeeds at a pseudopod Strike, it deals 2d6 acid damage to a metal item the target is wearing or holding, ignoring the item's Hardness. If a creature uses the Shield Block reaction with a metal shield against a rust ooze's pseudopod attack, the shield is automatically broken, but no other item is rusted.
Tetanus (disease) — An infection introduced through open wounds, tetanus can produce stiffness, muscle spasms strong enough to break bones, and ultimately death.

WORKS WELL WITH

SniperLAND / AQUATICThe Ooze's durable body and slow speed create a stationary bulwark, absorbing melee attention while a Sniper fires from range without exposing themselves to the enemy front line.
WeaverLAND / AQUATICThe Weaver's forced movement funnels enemies into the Ooze's reach, where the Rust critical effect threatens their equipment and Tetanus imposes long-term ability-score penalties.
MenderLAND / AQUATICThe Ooze's high HP pool and low AC make it a predictable damage sponge that a Mender can sustain with single-target healing, eliminating the tracking burden of an evasive frontliner.
