From PHBII
1st level:
-Blade of Blood Your weapon does +1d6 damage, or +3d6 if you take 5 points of damage (the weapon literally drips with the corrosive blood of an alien creature)
-Bigby's Tripping hand: A hand trips the target, you could make it a tentacle fairly easily
2nd level:
-Increase Virulence: Increase the save DC of a poison by 2. (nastier stuff from another dimension?)
-Stretch weapon: Your weapon gains 5 feet of reach for one attack, It could easily turn into a tentacle (heh heh)
-Vertigo: Target has to make balance checks to move. (a maddening vision of impossible heights through open portals?)
-Black Karma Curse (Subject damages themselves with a melee attack)
- Cloud of Knives: Releasing a haze of razor-sharp spikes out of nowhere? perfect for the alienist.
-Drifts of Shalam: Create difficult terrain of Snow, leaves, or ash. or whatever alien landscape you can conjure up.
-Dimension Hop: A short-distance teleport.
-Kelgore's Grave Myst: Causes 1d6 cold / level, fatigue, ignores some SR (you could make it a eerie cloud of ethereal tentacles)
that's some good stuff there.
