One summoner in my adventure, wanted to create a thematic eidolon like Shiva of final fantasy (an ice manipulator like).So asked me if is possible to change a little the spells on the list of the major magic evolution adding some ice or water offensive spell taken from 3rd party books like Super genius guide to ice magic.
What do you think of this?
i didn't see the problem if the level of the magic is the same (3rd level)
