Elgar's Elemental Missiles

You create four glowing, elemental magical darts. Each dart hits a creature of your choice that you can see within range. An elemental dart deals 1d4 + 1 damage to its target. The darts all strike simultaneously, and you can direct them to hit one creature or several. The damage type is decided by the caster when the spell is cast, and all darts share the declared damage type. The damage is applied immediately, and there is no damage-over-time (fire darts don't start fires, but they do cauterize wounds).

The possible damage types include lightning (air), bludgeoning (earth), fire (fire), and cold (water).

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the spell creates one more dart for each slot level above 2nd.
