Lance Master (5e Feat)
From D&D Wiki
You have learned to put all of your weight into a charge, maximizing the carnage that follows your devastating attacks.
• If you move at least 20 feet in a straight line before making an attack with a lance, you add your strength modifier a second time to the damage dealt.
• Before you make a melee attack with a lance, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the damage.
