I am confused by a rakshasa with ten rogue levels's challenge rating.
Having ten class levels and being a ten hd creature, his challenge rating should be 15 (if rogue is not a key class for him) or 20 (if rogue is a key class). Yes the book and the SRD gives him a challenge rating of 14.
Am I calculating wrong?
And wouldn't rogue be a key class for him as rakshasa use their abilities to stealthily confuse their opponent?
EDIT: I edited out the proper name, as my players read this board.
