Thuul PR 8

Thuul Hive Matriarch

A Primus-Matriarch is the sole reproductive female of a Thuul colony; females occur roughly once in a hundred thousand births. She lays every egg of the colony, can live for centuries, and holds an authority that the Dominus-Patriarch's combat record does not override. She is kept in the brood chambers under permanent guard, and killing one ends the colony.

Traits

  • Brood Authority

    Thuul within 120 feet cannot be Charmed or Frightened, and add the Matriarch's Wisdom modifier to their damage rolls.

  • Federation Lore

    The Matriarch has advantage on Intelligence and Wisdom checks concerning anything that happened inside Federation space in the last three hundred years.

Actions

  • Ovipositor Lash

    +8 to hit · reach 15 ft.

    2d10 + 5 bludgeoning damage

    The Matriarch makes two Ovipositor Lash attacks. A creature hit by both is coated, and every Thuul within 120 feet knows where it is until the end of the Matriarch's next turn.

  • Command the Brood

    DC 14 Wisdom save

    Each hostile creature within 60 feet takes 8d6 psychic damage on a failed save, or half as much on a success. Thuul allies within 60 feet immediately move up to their speed toward a target of the Matriarch's choice.

  • Brood Shield Reaction

    When the Matriarch is hit by an attack and a Thuul is within 15 feet, that Thuul takes the attack instead, resolving it against its own Armor Class.
