CR of a 10th level Psion Illithid

[Thanee]

Is it just 10 + CR of Illithid?

Yes.

Edit: Love that piccy.

Technically yes, but you will find that it is in no way a CR 18 challenge.

My feeling is that for adding spell using classes to a creature it is more effective to treat it as if there were two separate beings and calculate the EL - so for a CR10 psion and a CR8 mind flayer, the final EL would be, what, 11? That might seem too low, but considering that a CR18 wizard or psion would have 9th level powers to throw around, while this psion 10/illithid only has 5th level powers... I think it is much closer to reality than just adding CR to class level.

After all, a single creature is normally doing one thing each round, while two creatures can help one another, provide covering fire, provide more targets etc. etc.

The Monster's Handbook from FFG has a system for CR modification that takes this approach. It looks good to me but I haven't used it myself. (I tend to play a great deal of D20 but run games using other systems.)

Intuitively I'd say 12 seems about right. 18 is surely too much.

I think CRs for classed creatures in general are a little wonky.

Monster's Handbook, you say... Hmm.
