Swarm. The swarm can occupy another creature's space and vice versa, and the swarm can move through any opening large enough for a Tiny insect. The swarm can't regain hit points or gain temporary hit points.

Magic Resistance. Micro Terrors have advantage on saving throws against spells and other magical effects.

Parasitic Mageslayer. The Micro Terror's sting carries an insidious venom, as well as quite a few eggs. Those hit by their sting attack must make a DC 12 constitution save or be inflicted with Mageslayer Venom. Those under the effects cannot speak, have disadvantage on constitution saves made to maintain concentration, and suffer 1d4 poison damage, as well as the poisoned condition for 1 minute. Upon rolling a natural 1 on this save, roll a second d20. In the event that this rolls below a 6, the target is paralyzed for 30 seconds. At the end of the creature's turn, they may re-roll this save, ending the effects on a success, unless the creature is suffering from paralysis due to the venom. While paralyzed, the target may instead roll a DC 14 constitution save at the end of their turn to end the paralysis. Creatures who die while under the effects of Mageslayer inflicted by a Micro Terror who are size small or larger are eaten from the inside out over the course of (1d100+X) minutes (X being the creature's size category times 3, 1 for small, 3 for medium, 5 for large, 10 for huge, 50 for gargantuan), after which a number of Micro Terrors emerge from the now fleshless corpse, dependent on the size of the creature. 1/2(1d2+X) swarms of Micro Terrors emerge surrounding the space of the dead creature.

Pheromone Marking. After being struck by or striking Micro Terrors, a creature must be cleansed by the Prestidigitation spell or similar, or be affected by pheromones for 1d4 days, during which any Micro Terrors within 300 feet are made aware of their presence and location.


Nightmarish Humming. Creatures either within 5 feet of 3 or more swarms of Micro Terrors, as well as those within a swarm for longer than 2 turns must make a DC 12 wisdom save at the start of each of their turns or suffer from the effects of fear. This fear persists until the creature can no longer see or hear a Micro Terror for one full turn.

Details

While most tarrasquespawn are simply creatures following instincts, the Micro terror inherited something far worse than direct destructive power from its distant progenitor. Despite being individually weak, these "insects" are just as much a natural disaster, if not more of one, than the Tarrasque. They are capable of communication, replicate en masse through the victims they leave behind, and also have almost every drop of malice that the origin of their species once did. If even one micro terror is found, the continent in question is completely locked down and purged of every last trace, before they have a chance at reaching critical mass and crossing the vast oceans.
