Elemental Surge

You release a burst of raw elemental energy towards a target you can see within range. Choose one damage type when casting: Fire, Acid, Lightning, Cold, Force, or Poison. Make a ranged spell attack against the target. On a hit, the target takes 2d8 damage of the chosen type. If the creature is vulnerable to that damage type, it also suffers disadvantage on its next attack roll.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, each target takes 1d8 extra damage of the type rolled for each slot level above 1st.
