I hope they bring back spells like Virulent Corpse Bomb from the first game. That one would make a corpse explode, and if any enemy nearby died to the explosion or within the next few seconds they’d explode too, and so on.

It wasn’t the best spell, but it fit the “mages are one misstep away from becoming eldritch abominations” narrative and damn did it make you feel powerful when it turned an entire room full of enemies into mist.
