Energy Javelin

  You cover a spear or javelin that you are holding with a sheathe of strong energy. For the duration, you can use your spellcasting ability instead of Strength for the attack and damage rolls of ranged attacks using that weapon. The weapon also becomes magical, and the damage die becomes a d8. Additionally, targets who are hit by this weapon must make a Constitution saving throw. On a failed save, the target is pushed back 15-feet in the weapon's direction of travel. If a target is pushed by this effect into an object, they take another d8 of Bludgeoning damage.
