At what level? To a single target, or to an area, or what?
Ideally, up to level 20, and to an area, but if single target deals a lot more damage, then go for it. Hopefully you'd be working alone, blasting off an evocation spell like Hyper Fireball or Ray of Heck your HP, but if a summon can just dwarf anything the wizard can do by themselves, then be sure to mention it.
Anything other than 3rd party is allowed.
However, a sort of level by level guide would be great, treat it as if you were going on a long campaign to become the best archmage.
