So, guys, I need advice once again.
Level 25 campaign, DM ruled that Half-Ilithids are allowed to take Illithid Savant, I have 8000 xp for LA buyback, and all WotC sources are allowed. Evil campaign, btw. DM ruled that I may, as part of my character concept, consume a Greater Doppelganger to gain Consume Identity, since part of the concept is based on the abilities of Alex Mercer.
Part of the character concept is as follows:
To directly quote it:
[spoiler]Goals:
Of course, since we start the game relatively alone, the mind flayer character I have would first have to establish an organization to further his goals. Then, after establishing said organization, he would then go out on a campaign to contain other mind flayers, to prevent any obstacles to his hegemony.
Afterwards, he will infiltrate the countries of that world with his organizations, setting in place crucial wars to weaken the world and fragment it politically and socially, and to sow despair and discord and engender in the "foolish masses" a desire for a leader charming enough and powerful enough to bring peace.
Finally, he will then arise as a "messiah", promising Paradise to the peoples, and crushing those who oppose him. After obtaining control of the world, he shall then undertake his penultimate goal: to become the agent of instrumentality by consuming all brains in existence, ensuring that all shall exist within one shared consciousness.
Personality:
During play, as I said in the first step of the plan, he will establish an organization. He will do so either by a) killing and assuming the identity of the leader of an already-powerful organization, or b) engineering an organization from the ground up, via selective murders and disguises designed to create a group of people all disgusted with the world's tendencies to lie and desiring that lies be abolished.
I would RP him as always in disguise, working with the other PCs, even pretending to be their lackey. At night, however, he shall go out and lure some unsuspecting girl, with the intention of first taking advantage of her flesh, then afterwards, in the afterglow, consuming her mind and spirit.
Since he is disguised, he shall adopt a humanoid form similar to that of the Hunchback of Notre Dame at morning, and Jasper Cullen at night.
Once every three weeks, however, he shall retreat in solitude to assume his natural illithid form, to review his plans, and to analyze himself and detangle himself from the personalities he subsumed.
By the way, Illithids are hermaphrodites. Which makes it better. After all, it is not only virgin females that he can rape then consume...[/spoiler]
The build thus far:
3 free LA to be used for additional templates, divided into one LA +1 template, and one +2 LA template (to be decided upon) due to 8k XP for LA buyback.
Levels 1-5 Half-Illithid
Levels 6-15 Illithid Savant
Levels 15-25
So, what classes, combos and feats would you suggest to improve the character's power and scope?
