Dekelcia's Dancing Blade

Seeing other wizards work, Dekelcia scoffed... "Surely we can do better, Mord, surely."

You create a sword-shaped plane of force that hovers within range. It lasts for the duration.

When the sword appears, you make a melee spell attack against a target of your choice within 5 feet of the sword. On a hit, the target takes 7d10 force damage + your spellcasting ability modifier.

As a bonus action on your turn, you can move the weapon up to 60 feet and repeat the attack against a creature within 5 feet of it.

At Higher Levels: When you cast this spell using a spell slot of 8th level or higher, the damage increases by 2d10 for each slot level above 7th.
