Sling Master

Prerequisite: Dexterity 13 or higher, Proficiency with slings

Thanks to extensive practice with the sling, you gain the following benefits:

Increase your Dexterity score by 1, to a maximum of 20.

Your damage die with a sling changes from a d4 to a d6.

You may make melee attacks without disadvantage using a loaded sling.

Weapon attacks made with a sling against a creature that is a larger size than you score a critical hit on a roll of 19 or 20.

You may use your bonus action to prepare a "wound-up" shot with your sling by building momentum. The first attack you make on your next turn with your sling uses 2d6 for its damage roll. While your "wound-up" shot is prepared you move at half speed and whenever you take damage, you must make a Dexterity saving throw with a DC of 10 or half the damage you take, whichever number is higher, to maintain your preparation.
