Sniper

You have mastered the art of camouflage 

• You gain proficiency in Stealth.
• You can spend 1 minute creating camouflage for yourself. You must have access to fresh mud, dirt, plants, soot, and other naturally occurring materials with which to create your camouflage.  Your movement speed becomes 0 when using this ability, and you gain the Prone condition.  You cannot use this feature of this feat again until you complete a short or long rest.
• If you are successfully camouflaged and hidden, missing a ranged attack does not give away your position.
