I updated the psi-like abilities, but have a question.
The standard aboleth has a lower manifester level for a few of its powers (ego whip, id insinuation). Do we want to keep these the same level for the greater aboleth, bump them by the same ratio (6 lower than normal manifester level), or drop the lower manifester level altogether.
Well, you definitely want to say it acts as if it has ranks, since Knowledge is trained only. I could go either way, I guess, though I want to standardize with the thendar, which isn't so many HD. And I think DMs doing advancement can scale abilities themselves, right?
They possess enslavement powers superior to those of common aboleth, having a range of 60’ and usable a number of times per day equal to the aboleth’s hit dice. The save vs. spells is at -4, and only a limited wish, wish, or alter reality spell can counter it (though enslavement ends if the aboleth is killed as well). If more than two miles ever separate slave and master, the slave is entitled to another saving throw (still at -4).
