With extensive practice you have mastered the art of sling combat, granting you the following benefits:

• Increase your Dexterity by 1, to a maximum of 20.
• You gain a +1 bonus to attack rolls made with a sling.
• As a bonus action, you can make a ranged weapon attack, with a sling. On a hit, roll a d4, and choose a creature within 30 feet of the target, that creature can use their reaction to make one weapon attack against the target, adding the number rolled to the attack roll.
• When a creature within 30 feet of you makes an ability check or attack roll, you can use your reaction to make a ranged weapon attack against the creature, with a sling. On a hit, roll a d4 and subtract the number rolled from the creature's ability check or attack roll.
