Actions
Breath Weapon (5 or 6, 50-foot cone). Ranged Strike DC 30 Reflex with 10d10 acid damage; halved on a success.
Mind Thrust (3 per 24 hours). Ranged Strike +19/14/9 (range 30 feet) with 8d10 psychic damage.
Psychic Crush (3 per 24 hours). Ranged Strike +19/14/9 (range 60 feet) with 6d6 psychic damage.
Swallow Whole (Tentacle). As a Single Action, a Neothelid can attempt to swallow a creature that is at least one size smaller which it has currently Grabbed with the listed Strike. This is an Athletics check against the target’s Passive Athletics. If it succeeds, it swallows the target, inflicting listed Strike’s damage in the process. Each round after being swallowed, the target automatically takes 8d8 acid damage. The swallowed target is considered to still have the Grabbed condition, while the Neothelid is no longer considered to have a creature Grabbed. A swallowed target can try to cut its way free with any weapon that is 1 bulk or less and deals slashing or piercing damage or can try to escape the Grabbed condition with double disadvantage like trying to climb back out. The Neothelid’s stomach has AC 32 and 31 damage is required to cut an escape out of its stomach. If a swallowed target cuts its way out, the Neothelid cannot use Swallow Whole for two rounds. If a swallowed target escapes through overcoming the Grabbed condition, it is treated as being back in the Neothelid’s mouth where it must spend an action jumping out or it will be in danger of another Bite attack and being Swallowed Whole again.
Tentacle. Melee Strike +19/14/9 (unarmed) with 5d6 bludgeoning damage plus Grabbed (DC 30).
