A mature neothelid is a gigantic worm scores of feet long and weighing tens of thousands of pounds. Although they understand Undercommon, they rarely communicate in a meaningful way.
Breath Weapon (Su): Cone of acid 50 feet long, once every 1d4 rounds; damage 14d10 acid, Reflex half DC 30.
Improved Grab (Ex): To use this ability, a neothelid must hit a creature with two tentacles during the same attack. If it gets a hold, it automatically deals tentacle damage and can attempt to swallow the foe.
Psi-Like Abilities: At will—body equilibrium, psionic charm (all targets, duration 15 days, DC 21*), clairvoyant sense, psionic levitate, read thoughts (DC 17*), psionic suggestion (seven targets, DC 17*), telekinetic force (500 lb., DC 18*), telekinetic maneuver (+4 bonus, DC 19*), telekinetic thrust (500 lb., DC 18*), psionic teleport, trace teleport, truevenom (DC 19); 3/day—mind thrust (15d10, DC 23*), psychic crush (6d6, DC 16**). Manifester level 15th. The save DCs are Charisma-based.
*Includes augmentation for the neothelid’s manifester level.
**Includes the inherent +4 save adjustment described in the power.
Swallow Whole (Ex): A neothelid can try to swallow a grabbed opponent of a smaller size than itself by making a successful grapple check. Once inside, the opponent takes 2d8+15 points of crushing damage plus 2d6 points of acid damage per round from stomach secretions. A swallowed creature can cut its way out by using a light slashing or piercing weapon to deal 25 points of damage to the stomach (AC 22). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out. A neothelid’s interior can hold 1 Huge, 2 Large, 8 Medium, 32 Small, 128 Tiny, or 512 Diminutive or smaller opponents.
Blindsight (Ex): A neothelid can use nonvisual means to ascertain all foes within 100 feet as a sighted creature would.
