Which one is right considering Area of Effect and playing with a grid?

Epic Sorcerer Spell Bombardment

Bonus spell damage

Hex Trigger

Thanks for the reply! Another random question if you’re feeling bored! Does Magic Missile trigger Hex? If yes, how many times? does hex require an attack?

Yes, Hex requires an attack to trigger. My understanding is that MM/Fireball wouldn’t count since you don’t roll for those
