Arcane Auto Shot

As you begin to cast the spell the metal begins to float and take aim with varying effects depending on the type of metal used, Conductive metal will cause piercing and Lightning damage, heat resistant will cause piercing and Fire damage, and if you can get the blueprints and a blacksmith to make them for you, the "Spell Casings" will cause piercing damage and go through up to 4 targets depending on armor level Metal armor will slow the spell down and lower the total collateral targets to 3, mythril and adamantite will lower the collateral targets count to a 2, and and reinforcement spell will bring the collateral target count down by 1.

Once this spell has reached lv 7(4d8), Lv8(6d8 and Metal armor doesn't slow down Spell Casings), lv 9(8d8 and Mythril and Adamantite don't slow down the Spell Casings)
