Sniping Position

Provided you take no movement on your turn, you gain the following benefits until the start of your next turn:

• Your normal and long range are doubled with ranged or thrown weapons you are proficient in.
• You can add an extra damage die to one ranged weapon attack made at disadvantage.
• When a creature attempts to attack you, you can use your reaction to add half your proficiency bonus to your AC and impose disadvantage on all ranged attacks made against yourself until the start of your next turn.
• Once per turn, you can add +10 to a ranged weapon attack roll, but the damage total for that attack is reduced by half.
