So, I've had an idea rattling around in my head about a setting that doesn't have any traditional spell-casting. Instead the only supernatural power the players have access to is the kineticist class.
On top of this other classes that do have minor spell-casting can pick a kineticist talent or gain a blast (at a reduced level) at any point they would gain a new level.
Additionally, I'd like to integrate something akin to the Unchained Stamina System, and Burn would reduce stamina, and characters who aren't using kineticist abilities would be able to spend stamina to boost their feats (and attack rolls).
Does this seem like a possibly workable system?
