Special Traits

  • Amphibious. The finngalkn can breathe air and water.
  • Death Gaze. When a creature that can see the finngalkn’s eyes starts its turn within 30 feet of the finngalkn, the finngalkn can force it to make a DC 12 Constitution saving throw if the finngalkn isn’t incapacitated and can see the creature. If the saving throw fails by 5 or more, the creature is reduced to 0 hit points, unless it is immune to the frightened condition. Otherwise, a creature takes 16 (3d10) psychic damage on a failed save. Unless surprised, a creature can avert its eyes to avoid the saving throw at the start of its turn. If the creature does so, it has disadvantage on attack rolls against the finngalkn until the start of its next turn. If the creature looks at the finngalkn in the meantime, it must immediately make the saving throw. If the finngalkn sees itself reflected on a polished surface within 30 feet of it and in an area of bright light, the finngalkn is, due to its curse, affected by its own gaze.
  • Earth Glide. The finngalkn can burrow through nonmagical, unworked earth and stone. While doing so, the finngalkn doesn’t disturb the material it moves through.
  • Keen Hearing and Smell. The finngalkn has advantage on Wisdom (Perception) checks that rely on hearing or smell.
  • Pack Tactics. The finngalkn has advantage on an attack roll against a creature if at least one of the finngalkn’s allies is within 5 feet of the creature and the ally isn’t incapacitated.
  • Pounce. If the finngalkn moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 12 Strength saving throw or be knocked prone. If the target is prone, the finngalkn can make one bite attack against it as a bonus action.


  • Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) piercing damage.
  • Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage.


This blue-furred foxlike creature has a feral intelligence in its eyes.

A hybrid creature born of eggs hatched by a curious oddity, an elderly rooster. Representative of a diseased land, the thing that is born from the egg begins as a worm but rapidly grows into a horror that combines the worst traits of fox, cat, and man. It will eat anything it can catch, including corpses, but will gleefully use its death gaze on any creature that is foolish enough to stare it in the face.

The finngalkn is immune to most weapons and requires silvered weapons or attacks from good-aligned creatures to slay it.

Earthbound. When the young are born, they immediately sink into the earth as a defense mechanism; and for good reason, as they are killed on sight. The one saving grace is that finngalkns are not immune to their own gaze and can thus have it reflected back on them with a mirror.
