What are the strongest summons?

So does anyone know how to get the best out of the Void Gate? Is it sensitive to higher-level mages? Is there any way to restore a feebleminded mage's magic so that he can go back to summoning? I've gotten a few nifty things out of the Gate, but they've all been pretty weak so far. I want to see what it can really do.

Void-caused feeblemind is only amenable to the usual cures for afflictions -- having a commander which can heal afflictions (e.g. Fairy Queen), remaining under a Gift of Health until it's healed, using the Chalice et al.

The priestly starspawns have the best chance of getting stuff without getting feebleminded, IIRC. The national hero Cthgul the Stargazer has an even better chance than your average priestly starspawn, but you get at most one... Astral magic matters too, I think.

Give 'em good guards, because the more successful summons they pull off, the better chance they have of getting fun monsters, and good bodyguards makes it more likely they'll live that long.

Greater Othernesses, Formless Spawn, and Vastnesses are pretty interesting.
