If you have an evocation wizard cast an evocation AoE spell around a neutral or ally, they now also die. I almost one shot Isobel

. So much for dipping into that to protect allies from lighting bolt.
If you leave a surface, allies can also walk into it post combat, die over several seconds, and bystanders will blame you. Thanks to Larian being hard at work, darkness builds now also get to experience the joys of that. Bg3 needs a massive patch to make NPCs smarter.
