Heel turner's Resolve

Showman's Chair. 

As a free action you may unstow a spectral chair made of your own will.

You may make attacks with this chair as if you were proficient with this improvised weapon

Once per turn, when you hit a target with a melee weapon attack using this weapon, you can imbue the attack with an additional effect:

Showman's Snare. The target takes an extra 1d6 force damage. If the target is a creature, it must succeed on a Strength saving throw or grappled by you.

You can use this feat a number of times equal to your Charisma modifier, and you regain all expended uses when you finish a long rest.
