Precision Throwing

After years of practice, you have uncanny aim with all thrown weapon attacks (including improvised weapons) that rely on precision. You gain the following benefits:

• Increase your Dexterity score by 1, to a maximum of 20.
• You do not suffer disadvantage from being too close or too far from your target.
• You do not suffer disadvantage when your target is behind 1/2 or 3/4 cover. 
• Whenever you throw a weapon (i.e. a bottle, stones, a dagger, etc.), reroll your attack roll until you achieve a 10+ on a d20. The result of this roll will be your attack roll. 
• You can throw two objects per action instead of one.
