Ashen Volley

You form ash, dust, and smoke into a triad of ember-like shards, firing each shard at a target within range. Make a ranged spell attack for each target, up to 3 targets. On a hit, the target takes 1d4 fire damage per shard targeting them, and bonus fire damage equal to your spellcasting ability modifier once per target. On each of your following turns during the duration and while concentrating on this spell, you may use your action to fire off another volley of shards against the original targets, requiring additional ranged spell attack rolls. This spell ends if you break concentration, or all original targets leave this spell's range.

At Higher Levels: When cast with a spell slot above the 1st, the damage of each shard is increased by 1d4.
