[sblock=OOC]
I'm a little discourage at how little we are doing to these things. Lets see if we can't make a dent here!

[/sblock]
Haros winces and the talons of the vrock pierce his flesh, but through force of sheer will, he summons another creature of the id behind the two vrocks that now engage him. The horrifying creature looks like a huge orb with the texture of a brain, with one huge eye, and many sinewy tendrils that have another small eye halfway down their length.
Haros holds firm at his grim situation. Though the two beasts could eviscerate him, he hopes his formidable beasts come in the clutch. Trusting that Jerrek now has things in hand, he directs both of his idbeats to lash out at the demons threatening him.
Quickly taking stock of the fact that there are 3 of these horrid creatures in the immediate vicinity, he considers it is time to resort to one of his most formidible abilities. He unleashes a psychic scream that lashes at the minds of the demons.
[sblock=Combat Actions]
Concentration check to continue manifesting when struck by vrock (DC 21):
Concentration check (1d20+19=26)
Summon the Soulshriver (stats below) into the 10x10 square behind v3 and v8.
Ultrablast for 14d6, manifesting defensively.
Concentration check (1d20+19=21). Not good enough. Expend my psychic focus to use my mantle ability to add +11 to any roll, making the total 32.
By my count, the ultrablast should hit v3, v6, and v8. Roll for damage:
Ultrablast damage(14d6=53)
and power penetration:
power pen on v3, v6, v8 (1d20+14=22, 1d20+14=29, 1d20+14=22)
3/3 on power resistance it looks like. 53 points of mind-affecting damage, will save DC25 for half.
Have the Psimech turn and full attack v8.
Attack on Vrock (1d20+13=33, 2d8+6=15, 1d20+10=24, 1d8+3=5, 1d20+10=13, 1d8+3=4)
The first two would hit the vrock, the third might hit an image.
Have the soulshriver do 5 attacks each on v3 and v8, tendrils as follows:
v3: psionic charm, psionic dominate, control body, detect thoughts, dismiss ectoplasm
v8: crisis of breath, disable, ectoplasmic cocoon, dissolving touch, (no power)
These are touch attacks, so should only need a 1 to hit.
Tendril attacks on v3 (1d20+11=16, 1d20+11=27, 1d20+11=26, 1d20+11=15, 1d20+11=20)
Tendril attacks on v8 (1d20+11=14, 1d20+11=26, 1d20+11=30, 1d20+11=31, 1d20+11=26)
Looks like 5 hits on each vrock; I'll leave it to you to resolve which hit images.
Those effects that get through are will save DC 18 to resist, and are augmented to 12th level. Damage is 1d4+3 each. Though it's a touch attack, it doesn't say it is non-physical damage, so unless you rule otherwise, I'll assume that they won't get through the DR. But if you need damage rolls, here they are:
Tendril attacks on vrocks (1d4+3=7, 1d4+3=5, 1d4+3=6, 1d4+3=7, 1d4+3=7, 1d4+3=6, 1d4+3=4, 1d4+3=6, 1d4+3=7, 1d4+3=5)
Also have the soulshriver close its brain lock eye. It can't affect me, the other elan, or the demons, but no sense risking the others.
Final action by calved off mind... if vrock v3 or v8 alive and not charmed/dominated/disabled in front of me, I'll direct a mind thrust at it. (No AoO possible)
Mind thrust dmg, power penetration roll (8d10=57, 1d20+14=23)
57 points, DC 23 save for none.
pp spent: 14 or 22; psychic focus expended.

Alignment: Usually chaotic evil[sblock=Description]This creature looks to be 5 feet across with wrinkled and convoluted skin—almost as if composed of naked brain tissue. Its rounded body contains only a single central eye and 10 tendrils that wetly sprout from its skin, each bearing a single eye halfway along the length. The creature floats in the air, and with its tendrils fully deployed, it looks like it’s hanging in a synaptic web. Soulshrivers are psionic monsters that kill with sizzling mind bolts.
These horrible, manic creatures represent an evolutionary offshoot of a parent race. They adapted better to developing the inner power of the brain than wielding arcane magic.
The stuff of nightmares, soulshrivers can speak telepathically to any creature within 60 feet that has a language.[/sblock]
Combat
Brain Lock Cone (Su): A soulshriver’s central eye continually produces a 60-foot brain lock cone extending straight ahead from the creature’s front. This functions similarly to the brain lock manifested by a 12th-level psion (DC 16). All humanoids in the area of Medium or smaller size who fail the save stand mentally paralyzed and cannot use their psionic powers; a new save is required each round. Once each round, during its turn, the soulshriver decides which way it will face and whether to make the brain lock cone active or not (the soulshriver deactivates the cone by shutting its central eye). Unlike a regularly manifest brain lock, the soulshriver need not concentrate to maintain brain locks on its affected foes.
Psi-Like Abilities: Unlike standard psionic creatures, a soulshriver can manifest only the psionic powers it knows via a synaptic tendril, which do not draw attacks of opportunity when so transferred. It can freely manifest a particular power only once every round. Even powers that normally have an area are transferred only to the touched target. On a successful touch attack, if the transferred power normally allows a save, the save is fixed at DC 18.
The psi-like abilities of a soulshriver are as follows: At will—
control body, crisis of breath, detect thoughts, disable, dismiss ectoplasm, dissolving touch, ectoplasmic cocoon, psionic charm, psionic dominate. Manifester level 12th; save DCs are Charisma based. Augmentable powers are augmented to the limit of the manifester level, if appropriate to the power.
Synaptic Transmission (Su): On a successful touch attack, each of the 10 synaptic tendrils can transfer a psionic power the soulshriver knows. The creature can easily lash all its tendrils upward, but its own body tends to get in the way when it tries to attack creatures in other directions. During a round, the creature can make five attacks against targets in any one arc other than up (forward, backward, left, right, or down). The remaining tendrils must attack targets in other arcs or not at all. A soulshriver can tilt and pan its body each round to change which tendrils it can bring to bear in an arc.
All-Around Vision (Ex): Soulshrivers are exceptionally alert and circumspect. Their many eyes give them a +4 racial bonus on Spot and Search checks, and they can’t be flanked.
Death Shrive (Ex): At death, the creature’s tendrils lash violently, while expending all remaining psionic power. All creatures within 20 feet must make a Reflex saving throw (DC 16) or take 2d10 points of damage (half damage on a successful save).
Flight (Ex): A soulshriver’s body is naturally buoyant. This buoyancy allows it to psionic fly as the power, as a free action, at a speed of 30 feet. This buoyancy also grants it a permanent feather fall effect with personal range.
