You have a +2 bonus to attack and damage rolls made with this magic weapon.

This bow has 3 charges. Upon firing an arrow, you can use a bonus action and use 1 charge to cast Silence at the location where the arrow stops. The bow gains 1d2 charge every day at dusk.

If you load no arrow in the bow, it produces its own, automatically creating one magical arrow when you pull back the string. The arrow created by the bow vanishes the instant after it hits or misses a target. An arrow that is fired this way is fired from the bow, moves through the air, and hits or misses the target with complete silence.  

Proficiency with a Longbow allows you to add your proficiency bonus to the attack roll for any attack you make with it.
