My group needs another primary caster (i.e., most attacks, actions in combat are ranged spells). What would be the best way to make a American Indian - style shaman (e.g., Deadlands RPG). He'd accomplish things, ideally, through summoning spirits of different kinds to perform actions. If he had to do HTH combat, it would be with the old two trusty Tomohawks.
It's not exactly summoning, since he doesn't summon a creature that then sticks around and done stuff. Since they can do things like heal, buff characters, curse opponents, etc.
Any ideas on how to make something as much like this as possible would be helpful.
