The Iron Sting is a free-to-play 4-star weapon available to all players. While there is no special unlock requirement, obtaining the actual weapon itself will require some grinding. That’s because the sword requires a Northlander Sword Billet, only available through weekly boss drops or as quest/exploration rewards.

Once you obtain a Northlander Sword Billet, you can use it to forge either the Iron Sting or Prototype Rancour. You should craft the Iron Sting if you have a sword character who focuses on creating elemental reactions or use Elemental Mastery in their kit.

Is the Iron Sting any good?

The Iron Sting is a niche weapon for sword users, as there are not many sword users who benefit from the Elemental Mastery substat. Unfortunately, most of the free sword options available to forge are not great for most characters.

Luckily, the Iron Sting has a few characters who take advantage of it well. Kazuha, in particular, benefits greatly from Elemental Mastery. This is a great F2P option for him, as he wants as much EM as possible. Bennett also has a niche DPS build that allows him to trigger elemental reactions and deal high damage, making Iron Sting his best 4-star option here.

Otherwise, it’s recommended to stick to weapons you pull from the Standard or Featured Banners.
