Arcane Blade

A weapon, imbued with an arcane energy that guides your strikes, appears in your hand. For the duration, you can use your spellcasting ability instead of your Strength for the attack and damage rolls for melee attacks using this weapon. This weapon may take the firm of any melee weapon that does not have the two handed or heavy properties and is regarded as magical. The spell ends at the end of one minute, if you cast it again or another spell which creates a magical weapon, or if you let go of the weapon.
