Lancer

You are a dangerous foe to face while mounted. While you are mounted and aren’t incapacitated, you gain the following while attacking a creature with a melee attack 

• You gain a +2 bonus to your initiative if you are mounted.
• If you move at least 30 ft. while mounted, you may make a melee attack using your bonus action, dealing your weapon damage plus X. Where X is the number of 5 feet you have moved this turn.
• After a creature have attacked you with a melee attack or melee spell attack, you may use your reaction to move 20 feet away from the creature without triggering an attack of opportunity from that creature.
