Asterisks go after the word they are amending / foot noting /whatever you call it (at least in my mind). So it should be disintegrate and fireball (forgot to add fireball) and then ray of frost. All the ones I spelled out in the actions. Shield is there to let you know its use is included in the CR.So I'm not quite sure what is going on here. Are you saying for example that you expect Azalin to cast a 9th level version of globe of invul? and then thunderwave at 8th level?
And yes, the intent is the CR assumes you are casting Fireball/disintegrate at 9th, then 8th, and then 7th level. That is why I gave those damages.
