Alright so I wanted to play an illithid but the 15 level monster class is way to much and of course just playing one gives way to big of a bonus.
So the DM suggested the Half-Illithid and its CR is 3. For a level 5 game this means my character would be a level 2. But we are allowed the Cr buy off method of every three levels I can buy off a Cr with a class level at 3 and again at 6th level. I heard its suppose to be half your CR rounded down but my DM is allowing the CR buyoff so at level 9 I buy off all my cr I am just gonna be a level behind the party.
What classes are best suited for a Half-Illithid I was thinking Arcanist and just fluff it as psionics. My DM likes Psionics but Psion doesn't seem as powerful and unless I talk him into a STP Erudite I am gonna miss out on a lot of my favorite spells.
This is a gestalt game, but the other side really does not matter as much I am more worried about my caster side.
