Well, if we go by ye old standard RPG, there wouldn't be an adjective. It would just be:

Lesser Summoning; Summoning; Greater Summoning; etc.

There really isn't a very good word in English that wouldn't come off as either redundant or silly (or both) for the standard ability. The ability name pretty much implies that, already. Still, if an adjective must be used, then going by the example progression you gave, maybe....

Higher, Major, Advanced

And that's all I could reasonably come up with after about 30min of thesaurus spelunking. If I had to choose, I'd go with Advanced, but honestly, I still feel it's all a bit of a reach.
