Emerald Shard

A shimmering emerald shard streaks toward a target within range and bursts in a spray of acid. Make a ranged spell attack against the target. On a hit, the target takes 2d4 acid damage immediately and half as much (rounded up) acid damage at the end of its next turn.

The spell creates more than one shard when you reach higher levels: two shards at 5th level, three shards at 11th level, and four shards at 17th level. You can direct the shards at the same target or at different ones. Make a separate attack roll for each shard. If multiple shards are fired at the same target, the later damage for each shard is added together at the end of the targets next turn.
