Genshin Impact Iron Sting guide: Ascension materials, passive effects, and best characters to pair with

Genshin Impact brings a new variety of weapons and artifacts for use, and keeping track of them is difficult. While Travelers can only obtain some weapons through banners, the game keeps adding craftable weapons. These craftable weapons can be useful when equipped with the correct characters.

With the new 2.8 update out, players might want to spend their Primogems summoning Kazuha from banners. One of the best weapons they can pair with Kazuha is an F2P craftable weapon called the Iron Sting. Here is everything players need to know about Iron Sting in Genshin Impact.

All you need to know about Iron Sting in Genshin Impact

Introduced in Genshin Impact 1.0, the Iron Sting is a 4-star craftable sword that cannot be summoned from any banner. The only way to get Iron Sting is to forge it from a blacksmith. Visit any blacksmiths in Mondstadt, Liyue, and Inazuma and interact with them to forge a 4-star sword. Players can always find the blacksmith near the Adventurer's Guild.

Here is a list of resources players will need to make their very own Iron Sting:

• Northlander Sword Billet x1
• Crystal Chunks x 50
• White Iron Chunks x 50
• Mora x 500

The only hindrance for players has to be obtaining the Northlander Sword Billet. Sword Billets are part of the RNG random rewards that players can receive after defeating their weekly bosses. Hence, unless players have some luck, they might not get a sword billet for a very long time. Players can also level up the Sacred Sakura tree to obtain a sword billet for Iron Sting.
