Special Attacks:

Constrict (Ex): On a successful tentacle attack, the stalking horror can constrict its target, dealing an additional 2d6+13 points of bludgeoning damage. A creature grappled by the stalking horror cannot cast spells.

Psionics (Sp): The stalking horror possesses innate psionic abilities. It has access to the following powers:

  • Disintegrate, telekinesis (Psychokinesis discipline)
  • Control body, inertial barrier, molecular manipulation, opposite reaction (Psychokinesis discipline)
  • Life draining (Psychometabolism discipline)
  • Body equilibrium, displacement, ectoplasmic form (Psychometabolism discipline)
  • Summon planar creature (Psychoportation discipline)
  • Astral projection, time shift, wrench (Psychoportation discipline)
  • Mind link, psionic blast (ultrablast), contact (awe), ego whip (inflict pain), id insinuation (invisibility), mind bar, mind thrust (psionic residue), psychic crush (phobia amplification), psychic drain (Telepathy discipline)

The stalking horror manifests these powers as spell-like abilities with a caster level of 12. The save DC for the abilities is 17 + the power’s level.

Spells (Sp): Once per day, the stalking horror can cast the following spells as a 12th-level defiler: wall of fog, fog cloud, mirror image, dispel magic, fireball, lightning bolt, spectral force, Evard’s black tentacles, ice storm, cloudkill, and chain lightning.

Special Qualities:

Aura of Fear (Su): All creatures within 60 feet of the stalking horror must make a successful Will save (DC 20) or be affected by an aura of fear. Affected creatures are paralyzed with fear for 2d6 rounds and cannot take any actions.

Invisibility (Su): The stalking horror can turn invisible at will as a free action.

Skills: The stalking horror has a +8 racial bonus on Hide, Listen, Move Silently, and Spot checks.

Alignment: Always chaotic evil.

I just realized it left out the type, I’m thinking Aberration personally.

Not bad. ChatGPT is useful, but you have to go through its output with a fine tooth comb.
