Hydaelyn

You unleash a surge of sorcerous energy at a creature or object within range. Make a ranged spell attack; on a hit, the target takes 1d8 damage of a type you choose: Acid, Cold, Fire, Lightning, Poison, Psychic, or Thunder. If you roll an 8 on the damage die, you can roll an additional d8 and add it to the damage, with a maximum number of additional d8s equal to your spellcasting ability modifier. The damage increases to 2d8 at level 5, 3d8 at level 11, and 4d8 at level 17.
