Some ground effects can be cool, but there's no way in my table top campaign every goblin would have elemental arrows and exploding flasks like they do in BG3. The effect should also burn out much faster as right now the DOT damage is more than high level spells. In its current iteration combat is too much like DOS for my taste.

-Remove ground effects from spells that don't have them - there's already enough ways to create ground effects.
-Reduce the amount of enemies that can cause these effects - i.e. arrows and flasks
-Reduce the duration of ground effects to 1 or 2 turns maximum.
