The Key of Khaj-Nisut is a 5-star weapon added in Genshin Impact Version 3.1. This weapon is highly niche and suitable for only a few characters in the game. But if you intend on using characters like Nilou, this weapon may be a valuable pick if you can spare the Primogems to pick it up. This weapon boosts Elemental Mastery and HP%, which does limit who can use this weapon, so consider your characters before deciding to pull on this weapon.

To obtain the Key of Khaj-Nisut, the weapon must be featured as an available 5-star weapon on the Weapon Event Wish banner. Unlike most 5-star weapons in the game, the Key of Khaj-Nisut is only available to pull through this method, meaning you cannot obtain this weapon in the Standard Event Wish or Character Event Wish banners. As of this writing, the Key of Khaj-Nisut is not available yet and will be available in the future.

Is the Key of Khaj-Nisut any good?

The Key of Khaj-Nisut is a niche weapon that’s not recommended to pull for unless you are interested in the upcoming character, Nilou. This is Nilou’s signature weapon and therefore is built to help her out specifically. The HP% secondary scaling is a stat rare for Sword characters, with most desiring other stats instead. Additionally, the passive does not supply enough Elemental Mastery to characters for general use.

However, this will likely be the best weapon for Nilou and is usable for other characters like Kuki Shinobu who also scales off of HP% and Elemental Mastery. It’s a highly specific weapon that you should only pull for if you’re a diehard Nilou fan. Otherwise, it’s highly recommended to simply skip this weapon and save your Primogems.
