TRAITS
Swarm Form
The Voidkin Swarm occupies a 10 ft. space but can move through spaces as narrow as 1 inch without squeezing. It can't regain HP via healing unless through void energy or absorption effects.
Whispers of the Void
At the start of each creature's turn within 20 feet of the swarm, that creature must succeed on a DC 16 Wisdom saving throw or take 2d6 psychic damage and have disadvantage on concentration checks until the end of its next turn.
Hive Consciousness
The swarm has advantage on Intelligence, Wisdom, and Charisma saving throws against magic. The swarm shares thoughts and memories between all creatures in the swarm instantly.
ACTIONS
Void Laceration
Melee Weapon Attack: +7 to hit, reach 0 ft., all creatures in swarm’s space
Hit: 5d6 slashing damage + 4d6 psychic damage.
If a creature fails a DC 15 Intelligence saving throw, it suffers a random short-term madness effect (roll on DMG table).
Consume Thoughts (Recharge 5–6)
One creature in the swarm’s space must make a DC 17 Intelligence saving throw. On a failure, the target:
-
Takes 6d10 psychic damage, and
-
Forgets the last hour of memory, losing access to one prepared spell (randomly) or a class feature (DM's choice) for 1 hour.
Shatter Cohesion (1/day)
The swarm explodes outward in a 30 ft. sphere. All creatures in the area must make a DC 16 Constitution saving throw or take 5d8 force damage and be blinded for 1 minute (save ends at end of turn). The swarm loses 20 hit points after this effect.

BONUS ACTIONS
Reform
If the swarm has at least 40 HP and has taken the Shatter Cohesion action, it may condense back into a singular mass, regaining its full AC and enabling Void Laceration once more.
