Aeolus' Sword Graveyard

You conjure many swords that spring up from the ground in a 10ft radius around a point that you can see within range. all creatures in the radius when it was cast have to make a DEX save or take 6d6 piercing damage. or take half on a success.

The area then becomes “sharp terrain” for an 3 turns. Creatures who attempt to move through it have to make a DEX saving throw or take 3 slashing damage per 5ft moved. Creatures who are pushed or otherwise forced to move through it have disadvantage on this save.

For each level of the spell slot used to cast this spell above 3rd you add an additional 1d6 to the initial damage, 1 additional turn to the duration of the sharp terrain and 1 additional damage per 5ft square moved through.
