Brine-Scrapper Goblin

•  Brine-Slicked Psionic Insulation. The goblin’s nervous system is calloused and calcified by constant immersion in elder brain amniotic fluid. It has Advantage on saving throws against psionic spells and mind-blast effects.

• Brain-Scent (Sense Thoughts). The goblin can pinpoint the location of any creature within 30 feet that has an Intelligence score of 3 or higher, regardless of physical barriers or darkness, unless protected by a mind blank spell or similar warding.

• Psionic Scavenger. When an Aberration within 30 feet dies or uses an ability that deals psychic damage, the goblin gains 3 temporary hit points as it laps up the residual psionic discharge.

•  Ceremorphic Needle-Spike. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) piercing damage plus 3 (1d6) psychic damage.

• Tadpole Jar-Sling. Ranged Weapon Attack: +4 to hit, range 30/120 ft., one target. Hit: 4 (1d4 + 2) bludgeoning damage plus 2 (1d4) acid damage from foul elder brine. If the target has an Intelligence of 6 or higher, it must make a DC 11 Intelligence saving throw or suffer psionic static: it cannot cast spells of 1st level or higher until the end of its next turn.

• Psionic Static Hiss (Recharge 5–6). The goblin taps into its cranium scar to release a discordant mental pulse in a 15-foot cone. Each creature in that area must make a DC 11 Intelligence saving throw, taking 5 (2d4) psychic damage on a failed save, or half as much on a successful one.

Synaptic Scuttle. The goblin takes the Dash, Disengage, or Hide action. If it is within 10 feet of an Aberration, it can break eye contact and vanish into shadow, immediately becoming Invisible until the start of its next turn or until it makes an attack.

Psychic Tether. The goblin targets one creature it can see within 30 feet that has an Intelligence score of 3 or higher. The target must make a DC 11 Intelligence saving throw.

• On a failure: A parasitic mental link is forged until the end of the goblin’s next turn or until the target ends its turn more than 30 feet away from the goblin. While linked, whenever the goblin takes damage, the tethered target takes half of that damage (rounded down) as psychic damage, and the goblin has Advantage on attack rolls against the tethered creature.

• On a success: The creature resists the link, and it is immune to this goblin’s Psychic Tether for 24 hours.

Psionic Feedback Lash. When a creature attempts to communicate telepathically with the goblin or forces it to make an Intelligence or Wisdom saving throw, the goblin violently recoils its thoughts. The triggering creature must succeed on a DC 11 Intelligence saving throw or take 4 (1d8) psychic damage and lose its reaction until the start of its next turn.
