Thunderstep

After casting this spell, the target receives any, or all of the following effects.

You gain 5 feet of movement speed. 

Your weapon attacks deal 1 extra damage as long as the weapon deals one of the following damage types. If the weapon deals multiple types of these damages, it deals extra damage in proportion to the damage type.  The damage type can be Bludgeoning, Piercing, or Slashing. (Thunder if the weapon does bludgeoning damage, Lightning for piercing,  and fire for slashing)

Additionally, once per turn, as a bonus action, you can instantaneously move 15 feet in any horizontal direction of your choice, this movement does not cost movement, nor does it provoke an opportunity attack. Once you use this effect, you lose all effects of this spell. Upon moving in this way each creature within 5 feet of the spot you moved to, aside from the caster and person moving, must make a Constitution saving throw, or take 1d4 thunder damage, and 1d4 lightning damage. This movement is instant, but not teleporting, so you cannot move through walls.
