When you roll a 20 on your attack roll with this magic weapon, the target takes an extra 7 damage of the weapon’s type.

Proficiency with a lance allows you to add your proficiency bonus to the attack roll for any attack you make with it.

You have disadvantage when you use a lance to attack a target within 5 feet of you. Also, a lance requires two hands to wield when you aren't mounted.
