Traits

Amorphous. The plasmoid can squeeze through a space as narrow as 1 inch wide, provided it is wearing and carrying nothing. It has advantage on ability checks it makes to initiate or escape a grapple.

Hold Breath. The plasmoid can hold its breath for 1 hour.

Actions

Multiattack. The plasmoid makes three Pseudopod attacks.

Pseudopod. Melee Weapon Attack: +6 to hit (with advantage if the plasmoid has one or more allies within 10 feet of itself), reach 10 ft., one target. Hit:11 (2d6 + 4) bludgeoning damage.

Reactions

Uncanny Dodge. The plasmoid halves the damage that it takes from an attack that hits it. The plasmoid must be able to see the attacker.

Lore

On occasion, due to some biological anomaly, a plasmoid balloons in size upon reaching adulthood (around the age of twenty years). Plasmoids who use their increased size and strength to boss around smaller, weaker creatures can easily end up in positions of power, surrounded by loyal underlings, sycophants, and would-be usurpers. A plasmoid boss might be the master of a guild, the leader of a criminal enterprise, the lord of a plasmoid community, or the captain of a spelljamming ship.…
