A certain wotc module has a level 2 party fight a suicidal enemy with Fireball in a small room. Also the fireball does necrotic damage just to make sure no one can resist it. Went exactly as you’d expect. I haven’t read the module myself so not sure if the DM messed something up or what. I thought it was hilarious but the other players all rage quit so that campaign ended there.
