Leaping Grapple

You can use an action to move up to 10ft and attempt to grapple an enemy that is your size or smaller. When you attempt to grapple in this way, you may make Dexterity (Acrobatics) check instead of a Strength (Athletics) check. If the enemy has not taken a turn in combat, you have advantage on the grapple roll. 

Savage Bite

You may make a bite attack against a target you have grappled as a bonus action. The attack modifier for this is your Dexterity Modifier + your Proficiency Bonus. The damage is 1d4 piercing at Rogue level 3, 2d4 at Rogue level 6, 3d4 at Rogue level 9, 4d4 at Rogue level 12, 5d4 at Rogue Level 15, and 6d4 at Rogue level 18. You regain Hit points equal to half damage done to the creature with this attack.

Natural Attunement

Starting at 9th level, you have advantage on all stealth checks against Beasts and Monstrosities.  You gain proficiency in Sylvan as a language.

Wild Fury

Once per long rest, as an action, you can call upon the spirits of nature to imbue you with a wild fury for one minute. You can roll an additional damage die on each your attacks, but you receive a -2 penalty to AC. It can be canceled using a bonus action.

Spirit Bondage

When you reach 17th level, You can grapple creatures that are two sizes larger than you. In addition, twice per short rest, if a creature were to break from your grapple, you can use your reaction to maintain your grapple on the creature.
