I think there should be a kingdom of “Bosses” and a trait can be if you “match 4 or more” you create a storm with that particular gem. So you get 4 of purple, you start a purple storm. I know this is just a scratch of the surface but maybe it’ll get some of you other’s with great creativeness to take the ball & run with it.
– Also, all “bosses” that are currently in the game also belong to the new kingdom. Think of it like the Greek Mythology. They had Olympus as their main domain but then they also had something else under their purview.
