@dungeons You confronted the Sahuagin! Here's the best guidance I can give. Thunderwave [3d8] is your best shot for a top damage spell. Melee, one-handed [1d6] would be good if you're confident about hitting, but otherwise avoid it. Ranged, thrown [1d6] is not recommended due to its disadvange. Running is an option but use your Wisdom score to check if you're able to survive the attack. Good luck and try to keep the Sahuagin from landing an attack on you!
