  • Magic Resistance. The vril-ya has advantage on saving throws against spells and other magical effects.
  • Vril Cloud. Once per day, the vril-ya can emit a cloud of vril vapor, filling a 10-foot-radius sphere of air or water around it. The first time on a turn that a vril-ya enters the cloud or if it starts its turn within the cloud, the vril-ya heals 2d8 damage. A strong current or wind can disperse the cloud.


  • Tentacle. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) psychic damage. If the target is Medium or smaller, it is grappled (escape DC 14).
  • Psychic Drain. The vril-ya makes one Tentacle attack against a Medium or smaller creature it is grappling. If the attack hits, the target takes 22 (5d8) psychic damage. The vril-ya will continue draining once the target reaches 0 hit points, forcing failures on death saving throws until the target is dead


A legless being with scintillating gold skin drifts toward you. Whisps of bluish vapor seem to indicate wing-like appendages emerging from its back. It extends a tentacle toward you.

Failed Experiments. Ancient Ankeshelian practitioners once thought to use vril to enhance elemental beings and inadvertently created the vril-ya. A vril engineer can extract 3d8 ounces of vril fluid from a dead vril-ya.

Mindless Hunger. These ageless abominations roam the deep oceans, psychically draining any sentient life they find. Occasionally, in their starvation, they roam inland.

Elemental Nature. A vril-ya doesn’t require air, food, drink, or sleep.
