In mobile (idk if it’s on pc) you can do “hunt dilophosaur” quest to get a ascended one

A classic, iconic ranged weapon. The Bow. Used with arrows to deal damage, it is also the second ranged weapon the survivor can unlock, being beaten by a slingshot, and is the first to be able to change ammo, from stone to Tranq

In mobile do hunt Dilo quest to get an ascendant or mastercraft bow which usually does more damage than a crossbow and occasionally more than a longneck rifle

I gota mastercraft bow from hunting dilo
