Rain of Arrows

You have mastered ranged weapons and can fire multiple arrows using your attack action. You gain the following benefits:

• You can nock up to 3 arrows using the shortbow or longbow.
• Before you make an attack with a ranged weapon that you are proficient with, you can choose to take a (-) penalty to the attack roll for each arrow that you nock above your first. (example: if you nock two arrows you must take a penalty of (-1) and for three arrows you must take a penalty of (-2). 

You can only use this feature once per short rest.
