Dextrous Versatility

You are able to combine your strength and agility to handle weapons in a way that raw power or dexterity alone cannot, gaining the following benefits:

• You may treat versatile weapons in which you are proficient as having the finesse property when wielded in two hands.
• You can make an Attack with a dart as an improvised dagger that deals 1d4 plus your Dexterity modifier piercing damage on a hit.  You may apply your proficiency bonus to this attack roll if you have proficiency with either daggers or darts.  If you are a monk, darts become monk weapons for you.
• You can use an empty sling as an improvised finesse weapon (a small whip, with a reach of 5ft) that deals slashing damage equal to 1d4 plus your Dexterity modifier on a hit.  You may apply your proficiency bonus to this attack roll if you have proficiency with either slings or whips.   (A loaded sling still counts as a normal improvised weapon as per the PHB p147)
