(Tri-Kreen)
ECL 1/Monterous humanoid 2 ... Ardent1/Totemist 2/Warmind 10/+4 X
The CPsi monster class for Thrikreen works here.
Not sure what you mean by "ECL 1".
In any case, the normal 2hd racial + 2LA = 4 levels;
and then LA buy-off takes care of the +2LA by level 20.
Opens up another level.
Warmind 5 is usually enough.
The Psi and MoI double class works, and on the Ardent side
without further help because of the 2nd level Warmind festing.
Thrikreen 2 / Ardent 1 / Totemist 2 / Warmind 5 / DualX 10
... gets to the 9s with some more CO-ing.
