Shinobu is a 4-star unit that has been a prevalent option for many Dendro reaction-based teams thanks to her ability to consistently apply Electro to her enemies and heal the on-field members during the battle. Interestingly, both her damage and healing scale off her Max HP; however, one would usually want more EM on support for Hyperbloom teams.

Fortunately, Shinobu can use the Key of Khaj-Nisut, which can provide her with a max HP bonus to increase her healing and EM without compromising her damage. She is the only character besides Nilou who can use all the stats and effects of this 5-star sword efficiently.

3) Layla

Layla is a 4-star Cryo character who can provide a powerful shield from her Elemental Skill. Her shield strength and damage from her talents scale off her Max HP, which limits her weapon options, and most fans usually end up using an Energy Recharge weapon on her.

The Key of Khaj-Nisut's passive effect will not be efficient on Layla due to her gameplay style. However, the HP% secondary stat can significantly increase her damage and shield strength, which makes the 5-star weapon from the Deshret Series the best overall option for the Cryo character.
