One of my players wants the ability to grapple other creatures at range when using a whip (think Indiana Jones wrapping his whip around things). I think this is a reasonable ability to have, but because it confers a mechanical advantage, I want to make this a feat. The text of the feat would read as follows:
You have trained extensively with the whip, allowing you to use it both within and outside of combat. You gain the following benefits:
- Increase your Dexterity score by 1, to a maximum of 20.
- When wielding a whip, you can attempt to grab another creature using your whip. To do so, make a Dexterity check to which you can add your proficiency bonus if you are proficient with whips contested by the other creature's Strength (Athletics) or Dexterity (Acrobatics) check. On a successful check, the creature cannot move away from you. On its turn, it can make a Strength (Athletics) or Dexterity (Acrobatics) check contested by your Strength (Athletics) check to try to escape. Once the creature has been grabbed, you can move in a direction opposite it and drag it with you at half your speed unless it is two or more sizes smaller.
- When wielding a whip, you may use its reach instead of your own on ability checks to grab or catch objects.
Does this seem balanced when compared to other feats?
