This movement doesn’t provoke opportunity attacks. Careful Aim Beginning at 11th level, you can shoot arrows with extreme precision. You can use a bonus action to aim carefully. For the rest of the turn, your ranged weapon attacks ignore half cover and three-quarters cover, and deal an extra 1d4 damage of the weapon's damage type on a hit. Extraordinary Stealth When you reach 15th level, you gain proficiency in the Stealth skill if you don't already have it, and your proficiency bonus is doubled for any ability check you make that uses that skill. In addition, once on each of your turns, if you are hidden from a creature and then hit it with a ranged weapon attack, the attack deals an extra 1d8 damage.
