Arboreal

Though Jund is mostly jungle, most of its settlements are found in clearings. The few that aren’t are found within the clustered trees and difficult terrain, along with all of the hostile creatures living nearby. Individuals who have spent most their lives within these settlements or jungles, have taken their fair share of tumbles, and have learnt from them. These individuals are used to falling, knowing how to now subconsciously minimize damage or make very effective jumps.
Skill Proficiencies — Acrobatics, and either Perception or Survival   You reduce all Fall Damage you take by an amount equal to your Proficiency Bonus.   If you willingly fall or make a jump, you ignore a number of feet from the fall equal to twice your Strength score (instead of x1).
