You channel raw magical energy into a melee weapon or a worn object on your hand and unleash a powerful strike towards a creature or object within range. Make a melee spell attack against the target. On a hit, the target takes 1d8 Force damage. If the target is within 5 feet of you, it instead takes 1d12 Force damage.

Cantrip Upgrade. The spell creates two strikes at level 5, three strikes at level 11, and four strikes at level 17. You can direct the strikes at the same target or at different ones. Make a separate attack roll for each strike.
