Rider

Your extensive experience in operating vehicles and mounting creatures have given you mastery on the art of riding.

• You gain proficiency on land and water vehicles. If you are already proficient with the vehicle, you add double your proficiency bonus to checks you make to operate it.
• When making Wisdom (Animal Handling) checks for negotiating with creatures you want to mount or making Charisma (Persuasion/Intimidation/Deception) checks when interacting with other creatures in order to obrain a mount, you add your proficiency bonus to the roll.
• You can mount any creature without the need for saddles or without it having an appropriate anatomy as long as it is at least one size larger than you.
• When you want to mount an unwilling creature, you can use the Attack action to mount it. If you’re able to make multiple attacks with the Attack action, this attack replaces one of them.
  
  The target creature must be within your reach. You try to mount the target by making a check instead of an attack roll: a Strength (Athletics) check contested by the target’s Strength (Athletics) or Dexterity (Acrobatics) check (the target chooses the ability to use). If you succeed, you creature is now mounted but is not controlled by you. All your melee weapon attacks to the creature will have an advantage as long as it does not have the Reach property. The unwilling creature you mounted can use an action to throw you off making the same contest.
