Defender's Stones

A defensive version of the Stone's Throw spell, the Defender's Stones spell launches a fist-sized stone at a creature within range. Make a ranged spell attack against the target creature. On a successful hit, the target takes 1d10 bludgeoning damage and is pushed backwards 10' in a straight line.

The spell creates more than one stone upon reaching higher levels: two stones at 4th level, three stones at 10th level, and four stones at 16th level. You can direct the stones at the same target, or at different ones. Make a separate attack roll for each stone.
