Gymnast

You have trained your body to be flexible and graceful. You gain the following benefits:

• You gain proficiency in Acrobatics.
• If you are wearing no armor or light armor, and are proficient in that armor, you can use your reaction to add your proficiency bonus to your AC against an attack made against you.
• If you use an action that requires you to make an acrobatic check or saving throw, you can use a bonus action instead.
• You gain the tumble and clamber actions:
- Tumble: You use your action to nimbly maneuver around or over creatures moving through their space. Creatures that you pass in this way cannot make an attack of opportunity against you until the end of your turn. You must use 5 feet of movement when passing through the space of a creature two sizes larger than you, and an additional 5 feet for every size larger than that.
- Clamber: You use an attack action to climb up a target that is a size larger than you or bigger by making a contested Dexterity (acrobatics) check against the target's Strength (athletics) or Dexterity (acrobatics) check (the target chooses the ability to use). On a successful attack, you climb the target, provided they have an anatomy to allow it. You have advantage against the target while you are clambering it. The target can use it's action to knock or shake you off, to do so they must succeed on a Strength (athletics) or Dexterity (acrobatics) check contested by your Dexterity (acrobatics).
