Alchemost

Alchemical Discharge: Each time the alchemost is struck by a weapon and takes damage, it discharges a random alchemical effect. Roll 1d6 and apply the following effects, but only one effect per turn can be discharged:

1. Acid Splash in a 20-foot cone. Each target in the area must make a DC 10 Dexterity saving throw, taking 10 (3d6) damage on a failed save, or half as much damage on a successful one.
2. Alchemical Fire Blast in a 10-foot radius. Each target in the area takes 7 (2d6) fire damage, and at the start of each of its turns takes another 3 (1d6) fire damage from the sticky flammable goo. A creature can spend an action to make a DC 10 Dexterity check, putting out the flames on itself or another creature within reach on a success.
3. Billowing Smoke in a 20-foot radius. The alchemost is considered to be heavily obscured for its next 3 turns, unless the smoke is dissipated sooner via heavy wind.
4. Alchemical Flash in a 60-foot radius. Each creature in the area that can see much take a DC 10 Constitution saving throw or become blinded until the end of its next turn.
5. Poisonous Cloud in a 20-foot radius. Each creature in the area must make a DC 10 Constitution saving throw or become poisoned for 1 hour on a failed save. On a successful save, the creature takes half as much damage and is not poisoned. 
6. Thunderblast in a 20-foot radius. Each creature in the area must make a DC 10 Constitution saving throw, taking 9 (2d8) thunder damage and becoming deafened until the end of its next turn on a failed save. On a successful save, the creature takes half as much damage and is deafened as above.

Amorphous: The alchemost can move through a space as narrow as 1 inch wide without squeezing.

False Appearance: While the alchemost remains motionless, it is indistinguishable from a pool of alchemical waste.

Pseudopod: Melee Weapon Attack: +2 to hit, reach 10 ft., one target. Hit: 7 (2d6) bludgeoning damage plus 3 (1d6) acid damage.
