General Feat (Prerequisites: Level 4+, Dexterity 13+, Proficiency with Whip.)

You gain the following benefits.

Expertise. You become an Expert with a Whip.

Skill Increase. Increase your Sleight of Hand modifier by 1, to a maximum of 20.

Whip Grab. When you have any Whip in your Inventory, add the item Grasping Whip, which can be used in its place. If the primary Whip is non-magical, Grasping Whip will not count as a magical weapon. 

Disarming Strike. When you are wielding a Whip, an attempt to Disarm a creature within reach of the weapon has Advantage. The Disarming Strike targets one hand, not the weapon or item itself. The DC for this attack is the creature’s Strength saving throw. A successful Disarming Strike with this feat incurs 3 points of Slashing damage, the weapon or item is dropped, and the creature may not grasp anything in that hand for one combat round.
