I have a idea on the magic/creating. When you create a sovereign you should be able to pick ONE element(since the game is called elemental). exp I want fire so I pick fire as my element now when I pick a or all of magic category they will reflect on the element I pick. exp2 since I pick fire and pick summing, now only summing stuff I can summon are fire and if I get a fire shard they will make me more powerful the more fire shards the more powerful I will get but it will be vise versia with everyone who has fire(or what ever element they pick). So in away it will make it more tactical and more stuff to fight over.

Let me know if this makes since!? If not ill try to explained it better!
