Ankhrav Hive Mother

CREATURE 8

Ankhrav hive mothers are fearsome predators that one can easily distinguish from the typical ankhrav not only by their greater size, but the presence of a large pair of razor-sharp, mantis-like arms.

Ankhravs are immense, burrowing, and insectile predators, considered by inhabitants of the rural areas of the world to be an all-too-common plague.

Tremorsense (Imprecise) 90 feet

Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.

Reactive Strike

Trigger A creature within the monster's reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it's using.

Effect The monster attempts a melee Strike against the triggering creature. If the attack is a critical hit and the trigger was a manipulate action, the monster disrupts that action. This Strike doesn't count toward the monster's multiple attack penalty, and its multiple attack penalty doesn't apply to this Strike.

Speed 25 feet, burrow 20 feet

Melee Mandibles +20 (acid), Damage 2d8+6 piercing plus 2d6 acid

Melee Acid Spit +17 (acid), Damage 5d6 acid

Armor-Rending Bite

The hive mother makes a mandibles Strike; if the Strike hits, the target's armor takes the damage and the acid damage bypasses the armor's Hardness.

Frenzy Pheromone

The hive mother unleashes a pheromone that causes all other ankhravs within a 100-foot emanation to become Quickened until the start of the hive mother's next turn, and they can use the extra action only for Burrow, Stride, or Strike actions.

The hive mother can't unleash the pheromone again for 1d4 rounds.

Spray Acid (acid)

The hive mother spews acid in a 60-foot cone, dealing 8d6 acid damage and 1d6 persistent acid damage (DC 26 basic Reflex save).

It can't spew acid again for 1d4 rounds.
