I had an idea and idk if anyone came up wt it yet so here it goes anyway.
We all know what global spells (bubbles) are, so how about a new set if bubbles we can learn in the future that would feature both 1 of the initial 7 schools and either shadow or star magic. The bubble should be a round constrained 'combustion', meaning that when the limit of rounds are up the bubble would explode doing some damage to everyone in the battle circle. Not sure if it should be star or shadow since it kind of reacts like backlash and it is round limited like auras, example 8 rounds then poof!!! Got the idea from the time limited battle with the Rat and obviously the already in game global fire spell Combustion. It also makes it possible to remove a bubble from the battle circle since we currently don't have a spell to remove bubbles. Obviously the effect it makes while active should be reasonable that makes it worth the damage it does. I hope you like this idea and discuss how to make it better.
