I wanted to see how far one could keep Color Spray potent... found that the Nagaji FCB stacks with Mesmerist's Mental Potency... for a max of +8HD @ 20... but that's still a level 20 Mesmerist picking on level 10-13 party.
So, I settled with a level 5 Mesmerist, and want to know what I can do better?

Mesmerist
FCB: Add 1/5 to the Hit-Die limit and the total number of Hit Die affected with each enchantment or illusion spell the mesmerist casts. This bonus stacks with the mesmerist’s mental potency class feature and is applicable under the same conditions as that ability.

DESCRIPTION
A vivid cone of clashing colors springs forth from your hand, causing creatures to become stunned, perhaps also blinded, and possibly knocking them unconscious. Each creature within the cone is affected according to its HD.
2+2=4 HD or less: The creature is unconscious, blinded, and stunned for 2d4 rounds, then blinded and stunned for 1d4 rounds, and then stunned for 1 round. (Only living creatures are knocked unconscious.)
3+2 or 4+2 = 5 or 6 HD: The creature is blinded and stunned for 1d4 rounds, then stunned for 1 round.
5+2 = 7 or more HD: The creature is stunned for 1 round.
Sightless creatures are not affected by color spray.
A heavens oracle w/awesome display is better for the HD limit. +Cha to that may not be significantly better at level 20, but at level 5 it's worlds better. Possibly even too good for a monster aimed at the party... that's a serious problem for either the oracle or the mesmerist. If they get lucky then they can stunlock most of the party. Win or lose that could be pretty boring for those so stunlocked.
