[@Scio] Well I normally do Creatures/monsters and Weapons, but for a roleplay like this I'll probably stick to primarily Creatures/monsters. He'll have a limit to how many things he can have out at once which would slightly depend on what he summons. Like summoning a raptor to ride on would be easier than summoning say a mammoth. or summoning something like a goblin would be easier than an ogre. as examples. So basically be living Creatures of some verity, and the stronger the creature harder be for him to summon or control without a lot more training to improve himself. If you rather me restrict this even more a certain way do tell me.
