Interesting one here. Ugh, so many psionic monsters online. Still, not all that psionic-y in flavour.
- Huge Aberration (extraplanar) with 10 ft reach (disappointing it isn't innately 15).
- 5 RHD (d8 hp, medium BAB, good Will save, and 2 skill points/"level").
- Fly 80 ft (good).
- +6 natural AC.
- 6 tentacle slams (1d8).
- Constrict, improved grab: huge size and +6 Str should make you a respectable grappler.
- Mind drain: ranged 1d4 Int drain, Will save to avoid.
- Psionics: 3/day Daze Monster, Feather Fall, and Shatter. Not terrible, but not all that powerful.
- Darkvision 60 ft.
- SR 16: relevant at your starting level, but will fall away as you level.
- Str +6, Dex +4, Con +8, Int +10, Wis +2, Cha +6: net +36, no penalties!
- Smallish racial skill list, especially when you figure in that Int bonus. The list is a little underwhelming, but not totally useless.
Non-humanoid body type. A generous DM might let you use body-slots similar to a Grell. No language or ability to speak mentioned.
Huge size for 5 HD is already a pretty good deal. Flight as a high rate and good maneuverability is also pretty sweet. And those ability mods! Throw in 6 natural attacks, and innate grappling options. It's other special abilities are nice, but not amazing - although Mind Drain could be pretty effective at shutting down low Int/low will save enemies. [edit] Just realized this is a free, or maybe swift, action. That's pretty darn good. [/edit]
Progression? Martial adept could be good for these guys. Or with that Int modifier and 6 attacks, maybe Skillmonkey sneak-attacker?
I'm totally going to use these as a DM, or maybe in a VC in the future. Huge creatures for 5 HD/CR5 aren't all that common.
I'll agree with +2.
I picture them as looking vaguely like the Ocularon:
