Magic Mining

By making contact with the earth, you’re able to draw together the metal within it, forming 100 g of metallic dust in your hand. If you already have 100 grams of metallic dust, you can cast this cantrip again to shape that metallic dust into a piece that can be used as an improvised weapon with the light, thrown (60/120 feet), and finesse properties. For the duration of the spell, whenever you make a thrown attack with this weapon, you can use your bonus action to make it fly back to your hand.

This piece deals 1d6 of a nonmagical physical damage type of your choice. When the spell ends, you must decide whether to keep the piece formed or return it to its metallic dust form.

This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6). Upon reaching 11th level, the damage becomes magical.
