Need help finding the right monster of template...

[Knishook]

I'm trying to find the right monster/creature/template combo to represent a mass of pure magic that has had centuries to develop sentience.

It for the most part represents itself in a humanoid shape and has limited emotions. Kiiiinda like a fantasy AI made of malleable magic.

If anyone saw Justice League Dark, kinda like the house of mystery's spirit Orchid.

Any ideas or recommendations?

Take a construct, give it mental stats and make it ethereal, or give it a specific type of DR.
I would replace the slams with wild magic type effects.
What type of challenge rating are you looking for?

would recommend a combination of these 3 ai elemental infused advanced re flavor the elemental infused to be more in line with what your looking for, the ai template for the ai feel and the advanced template to shore up the stats

CR between 6-12, as i am just gonna insert it when it fits best, so realistically anything fits. Also plan was a non lethal fight to gain an ally (support role).

Ill whip something up trying both these suggestions :)

Any more will be appreciated ;D
