Arcane Bombardment

You create five glowing darts of magical force drawn from the Far Realm itself. Each dart strikes a creature of your choice that you can see within range. A dart deals 2d4 + 4 Force damage to its target. The darts all strike simultaneously, and you can direct them to hit one creature or several. For the next 3 rounds, the darts don't disappear unless counterspelled, behaving as if the spell was just cast, each dart dealing an additional 1d4 + 4 force damage each round.
