Thrown Weapon Master (GH)

You excel at thrown weapons and gain the following benefits:

• When you take the attack action to throw a weapon with the Thrown property, you may immediately use a bonus action to make two more attacks with a Thrown weapon. These must also be thrown attacks. You may use this ability a number of times equal to your dexterity or strength modifier per short rest.
• If you throw a weapon as part of an attack, you may immediately draw another onehanded weapon as part of that attack.
