Master Slinger

You have mastered the art of slinging and learned to perform special combat manoeuvres. You gain the following benefits:

• Increase your Dexterity score by 1.
• You are able to skillfully reload a sling without requiring a free hand.
• Being within 5 feet of a creature allows you to flail a loaded sling as a melee weapon. A melee sling attack doesn't impose disadvantage on your attack roll. Once successfully hitting a creature, roll a [roll]1d20[/roll] to determine if your ammunition has fallen out of the sling cradle. A roll of 11 or higher means you keep the ammunition.
• You may use a Bonus Action to whirl around a loaded sling and build momentum for your next attack. Your very next shot has its range increased up to 320 feet and doesn't suffer disadvantage from long range attack rolls. Whilst whirling, your movement speed is halved. Undergoing sudden movements may destabilise and end your whirl.
