Its only fair that players are able to re-summon creatures by doing quests that allow the wizard to gain the spell during gameplay. For example the firecat that opens dragon's mouth, the firesnake in cyclops lane, the heckhound in olde town, etc. These missions are exciting and deserve to become another form of dugeons!
While all the dungeons are repeatable once you've completed it for the first time, NONE of the quests are.
You want to see the Firecat again? Cast it at your opponent.
Quite frankly, if you keep summoning these guys outside of a battle circle, they would be less and less inclined to help you out -- labeling you an annoying pest.
