Genshin Impact: Compound Bow - How to get it, stats and materials for ascension

The Compound Bow is a 4-star bow available to all players. While there is no special unlocking requirement, getting the weapon itself will require some grinding. The sword needs a Northlander Bow Billet, which is only available via weekly boss drops or as mission / exploration rewards.

Once you have a Northlander Bow Billet, you can use it to forge the Prototype Crescent or Compound Bow. The compound bow is designed for physical carries, which is somewhat counterintuitive due to the lack of Bow characters that rely on physical damage.

Is the compound bow okay?

The problem with the compound bow is the lack of physical DPS characters that use a bow. There is only one character who can use an off-meta physical DPS build. Otherwise, the compound bow will always be overshadowed by the Crescent prototype as a free-to-play weapon.

The only character who could actually use the compound bow is Fischl. She has an out of meta physical DPS build, which allows her to use compound arc. Even so, the Prototype Crescent is still a stronger option. (The compound bow will win if you don't activate the Prototype Crescent passive, however.)
