Traits

Devil’s Sight

Harvester Venom

The koralk produces a potent poison that liquefies the innards of those affected by it. Every hour that elapses after a creature succumbs to this poison, it must succeed on a DC 17 Constitution saving throw or take 7 (2d6) poison damage, and its hp maximum is reduced by that amount. Creatures with resistance or immunity to poison or the poisoned condition can be affected by this poison. Such creatures have advantage on the saving throw.

Magic Resistance

The koralk has advantage on saving throws against spells and other magical effects.

Steadfast

The koralk can’t be frightened while it can see an ally within 30 feet of it.
