It may be a shock, but weapons are important Genshin impact, and know how upgrade weapons is essential to your success. The process is not complex, although it will require a lot of unnecessary gems and weapons.
Upgrade weapons in Genshin Impact by giving them other weapons and enhancement gems.
In Genshin Impact, your weapons will increase in power and level as you upgrade them, so it's important to keep the ones you love up to date. Old or junk weapons and enhancement gems (discovered in the world or crafted at the blacksmith) are used to upgrade weapons, so don't be afraid to loot everything you see. Once you have the materials to upgrade your weapon, enter the character menu, then select “Weapon” for the character whose weaponry you want to upgrade. From there, you'll have a few options, but for now we'll focus on the "Enhance" tab.
In this menu, you will see a few items. First, the weapon's level and stats will be displayed in the upper right, followed by the "Enhancement Materials" segment below. You can choose your materials in two ways. The first method is via “Auto Add”. This is a catch-all method, so if you have certain items you don't want to destroy, you'll want to use the second method and manually select each item for weapon enhancement via the six blocks below it. Otherwise, select the grade of materials you want to use and select “Auto Add”.
Whether you used 'Auto-Add' or chose each item by hand, you'll see the potential level and stat increase at the top, and the required 'Gold' (Mora, in Genshin Impact) at the bottom by 'Upgrade' button. If you have the coin, you can click “Upgrade” to discard these items for advertised boosts.
Keep in mind that the higher the level of your weapon, the higher the quality of the items you will have to scrap to boost it even more effectively. Also, there are level gates for weapons that will require 'ascension' to overcome, which will require a set amount of rare materials. The first gate is at level 20. Genshin Impact won't allow you to upgrade weapons until you go through the Ascension gate, so don't worry about accidentally dropping items for an upgrade of the berth.
