You're actually so right. I'll risk dying in a game just to get one more enemy in a single blast, especially if there's any bonus for getting a combo at all. Even as small as a little sound effect for getting 6 instead of 5. Something in my brain just says "Risk the run, it'll be worth it."
See, I know someone that would use that kind of item just for the chance of causing problems. The gain is nothing in comparison to the chaos he could cause. Are they the same? This seems like a common thing.
But yes! AOE in the active battle and turn based battle systems will be assured after hearing that. I'm also very excited to add in the ice rain and fire rain spells along with the AOE trap spells like acid pool. I'm sure they'll all need intense balancing, but it's going to be so fun seeing how players use them!!
