Leonardo's Projected Force (5e Spell)
From D&D Wiki
|Casting time:||1 action|
You create four balls of force that circle your person. As a bonus action on each of your turns for the duration, you can hurl one of the balls at a creature or object in range at which point it disappears. Make a ranged spell attack against the target. On a hit, the target takes 2d6 + 1 force damage.
If you are attacked in melee whilst there are balls circling you, the attacker must make a Dexterity save or be hit by one of the balls for 2d6 + 1 damage. The ball then disappears.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you create one additional ball for each slot level above 3rd.
