You invoke a lance made of force and light. The lance glows brightly, providing light as a lantern. You are considered proficient with this weapon, and it has the same weapon properties as a nonmagical lance.    On a successful melee attack with the lance, you deal 1d12 force damage and 2d8 radiant damage. You can perform a charge attack with the lance. If you move at least 20 feet straight toward a target and hit with the lance on the same turn, you double the damage of the attack.
