Another Acrobat Feat

You're extraordinarily agile and dexterous, allowing you to bend, contort and control your body in ways that almost seem inhuman:

• Increase your Dexterity score by 1, to a maximum of 20.
• Increase AC +1 if wearing NO ARMOR.
• You gain proficiency +4 in the Acrobatics skill.
• Modified Grapple. The DC for the saving throw and any escape attempts equals 8 plus your Dexterity modifier and Acrobatics Proficiency Bonus. This grapple is possible only if the target is no more than one size larger than you and if you have a hand free to grab it.
• Modified Climbing and Jumping, you can substitute your Dexterity for your Strength and your Acrobatics for an Athletics check. You can determine your jump distance using your Dexterity rather than your Strength.
• As a Reaction because you have erratic movement your are difficult to pin down during a fight. You can use Skirmisher Jumping variant, using your standing jumping skills to get away as a reaction when an enemy ends its turn within 5 feet of you. This movement doesn’t provoke opportunity attacks or
• or use an Uncanny Dodge on a DC 15 for Acrobatics. When an attacker that you can see hits you with an attack roll, you can take this Reaction to halve the attack’s damage against you (round down) once per Short Rest.
