Jumpy

You are particularly adept at traversing difficult terrain and jumping. You are able to save yourself from falling with quick thinking and grabbing reflexes.

• You gain proficiency in Acrobatics. If you already have proficiency in Acrobatics, your proficiency bonus is doubled for any ability check you make that uses it.
• Difficult terrain caused by uneven, slippery or overgrown terrain does not cost you extra movement.
• You may use Dexterity instead of Strength when determining the distance with long and high jumps. 
• You have advantage on Dexterity saving throws made to avoid falling off of objects or vehicles or into holes or pits. This does not include being knocked prone.
