Firm Arrowheads are a resource in Genshin Impact that can be dropped by Ranged Hilichurls. The crossbow-wielding enemies can often be found at Hilichurl camps, or random spawns out in the world.
They will be needed to ascend Amber, Diona, Fischl, and Xiao, and weapons like the Aquila Favonia, Raven Bow, Stringless, and Viridescent Hunt. You will come across them a lot while playing the game, but if you need to farm them, it can be a little awkward to try and remember exactly where to find these enemies.
If you need them fast and don’t want to farm them, you can purchase them from the Paimon’s Bargains tab of the Shop for Masterless Stardust, although we recommend farming everything you can instead of spending these valuable currencies on them.
On the maps below, you will find the location of different Hilichurl camps in Mondstadt where you can farm for Firm Arrowheads. They are not a guaranteed drop from ranged Hilichurls, but they are quite common.
It’s also important to remember that Firm Arrowheads can be upgraded to Sharp Arrowheads, and Sharp Arrowheads can be upgraded to Weathered Arrowheads at the Alchemy bench in Mondstadt or Liyue. You will need 3 of the lesser type to upgrade to the greater type.
