Spell blade

During a short rest you choose an element to bound to your spell blade: fire, frost, lightning, thunder, or acid. The spell blade deals 1d4 extra damage of the chosen type. This damage increases to 1d6 at 5th level and 1d8 whenever you receive your improved smite ability.  

As a bonus action you can have it appear in your hand from anywhere on the same plane or you can teleport to it if is within 20 feet.

Your divine smite changes to to an arcane smite with the damage type corresponding to the one bound to the spell blade.

Arcane bonding

During a long rest you may transfer the magical effects of one magic item on your person to your spell blade. The magic item becomes a mundane item until your spell sword transfers the effects of another magic item or you choose to end the effects. Your spell blade may only be bound to one magical item at a time.
