When you take this feat every weapon you are using that doesn't have the Heavy property, gains the Thrown property and a range of (40/80), and all weapons that already have the Thrown property gain an extra 20ft added to their range, and Advantage on attack rolls. You may also throw ammunition like this with no modifiers.

If you have no weapon in your hand you may take the dash action as a bonus action, and move to the nearest weapon you can see that is not being held(this include weapons stuck in creatures.) and pick it up, if it is stuck in a creature that creature takes 2d4 slashing damage. Dashing like this doesn't invoke opportunity attacks. You can climb at no penalty if the weapon is at the top of or imbedded in a wall.
