False Appearance. The metallic ooze is indistinguishable from a pile of coins as long as it remains motionless.

Irritating Fumes. If a metallic ooze takes fire damage, it emanates a cloud of semi-transparent vapor that irritates the eyes and respiratory system of living creatures within 10 feet of it. All creatures other than undead or constructs within the area must succeed on a DC 15 Constitution saving throw or take 10 (3d6) acid damage and be poisoned for 1 minute. A poisoned creature can repeat the saving throw at the end of each of its turns, ending the effect on a success. The cloud disperses in 1 minute, or can be dispersed by a moderate or greater wind.

Spider Climb. The metallic ooze can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Actions

Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 3) bludgeoning damage plus 18 (4d8) acid damage, and the target must succeed on a DC 15 Constitution saving throw or be poisoned for 1 hour.
