There are several ways to acquire new weapons in Genshin Impact. You can use wishes to purchase a variety of items, while potentially receiving a new character that you can use in your party. There's also the ability for new weapons to drop from creatures and from inside chests you can find while exploring the wild. You can also go to the main town, Mondstadt, and talk to the blacksmith at the entrance to town to have him craft new weapons for you. But first you need to complete a quick task for the blacksmith.
When you initially speak with the grumpy blacksmith, they ask you to locate pieces of iron ore so they can use it to craft new weapons for your characters. You can find these chunks of ore almost anywhere in the game. All you have to do is find the side of a hill and look for the large rocks resting on the side. You can hit them using any of your weapons to regularly smash them. Once their health is gone, they decay into a type of ore, most commonly large chunks of iron ore. Buy enough and bring them back to the blacksmith.
Share the items with the blacksmith, and he can now craft your weapons as soon as you have enough resources. The majority of the weapons he crafts for you will be available once you receive certain items. Most of the best gear can be accessed once you defeat bosses, so you have to face strong opponents in Genshin Impact so that the blacksmith has the right ingredients to craft good weapons for your characters.
