Blindfold of the Sharpshooter (5e Equipment)

Wondrous item, very rare

A simple piece of black cloth that looks as if not even a hint of light can pass through it

While wearing this blindfold you are blinded but are aware of everything further than 30ft. away.
The long range of any bow crossbow you wield is doubled and your attacks ignore half and three-quarters cover.
On a critical hit with a ranged weapon at long range deal 3 times damage instead of double.
