Arcane Forge

You touch an object, reinforcing its strength and enhancing its punch. It becomes a simple weapon you are proficient in, uses a d10 for its damage die, and uses your spellcasting modifier for attack rolls and damage modifiers. Additionally, you may use your action to release the spell early, causing an eruption of the remaining power. You can throw the object to a space within 20 feet of you, where it detonates in a 10 foot radius. Creatures in this radius must make a Dexterity Saving Throw against your Spell Save DC or take 3d10 force damage. On a successful save, they take half as much. Regardless, the object is destroyed and the spell ends. This eruption does not occur if the spell ends in a different way.
