Electrical Grid

You reach out and create lines of conductive material along the surface of the ground around you. You create 60 feet of metal that is 1mm thick, this metal can be produced as a straight line out from you or arranged as a pattern of 5 feet long segments. These segments can be arranged in any shape, but each segment must have one end connected to you or to the end of a series of segments connected to you. Segments can only connect end to end and cannot cross each other. You can make a single grid using the full 60 feet, or multiple patterns using a portion of the material. When you cast this spell, and as a bonus action on subsequent turns, you can send an electrical charge along any segment you are within five feet of, as well as any segments they are connected to. Any creature within five feet of a charged segment must make a Dexterity saving throw. On a failure, the creature takes 4d8 lightning damage and cannot take any reactions until the start of it's next turn, on a success, they take half damage.

At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th and you gain an additional 10 feet of material.
