Xaihi's Best Essences

Essences are one of the repeatedly farmable ways to further boost the weapon effects of your Xaihi. Which area and essence you will want to farm will depend on the weapon you are playing, as not all Essences are compatible with every weapon. Essences will increase the stats of your weapon, as well as enhance the passive effect it provides.

• Freedom to Proselytize: Will, Treatment Efficiency Boost, and Medicant, farmable in Power Plateau, Wuling City, Qingbo Stockade, Sword Vault Dale, and North Wuling Exclusion Zone.
• Detonation Unit: Main Attribute, Arts Intensity Boost, and Detonate, farmable in The Hub, Origin Lodespring, Qingbo Stockade, Sword Vault Dale, and Yinglung Pass.
• Stanza of Memorials: Intellect, Attack Boost, and Twilight, farmable in Wuling City, and Marker Stone.
• Chivalric Virtues: Will, HP Boost, and Medicant, farmable in Power Plateau, Wuling City, Qingbo Stockade, Sword Vault Dale, and North Wuling Exclusion Zone.
• Fluorescent Roc: Will, Attack Boost, and Suppression, farmable in The Hub, Originium Science Park, and Yinglung Pass.

Essences can be further upgraded through a system called Etching which will be a long-term investment due to how much Sanity it takes to fully max out a weapon. You may therefore want to farm and Etch Essences for a signature weapon already if you plan on getting it in the near-future, even if you do not have the weapon yet. A simple +1/+1/+1 Essence for a temporary weapon like Fluorescent Roc will be good enough until you can get your hands on Chivalric Virtues or Freedom to Proselytize.

Best Gear for Xaihi

LYNX

3-piece set effect: Wearer's HP Treatment Efficiency +20%. After the wearer gives HP treatment to an allied target, that target also gains 15% DMG Reduction against all types of DMG for 10s. If the said treatment exceeds the target's Max HP, the target gains 30% DMG Reduction against all types of DMG. The aforementioned effects cannot stack.

3-piece set effect: Wearer's HP +1000. After the wearer applies Amp, Protected, Susceptibility, or Weakened, other teammates gain DMG Dealt +16% for 15s. This effect cannot stack.

Leveling Gear for Xaihi

While the above gear set is the optimal choice, it might take you some time before you will be able to craft it. Below is a more early and mid-game set that we recommend until you've reached the pinnacle of craftsmanship.

Mordvolt Resistant

3-piece set effect: Wearer's Will +50. When the wearer's HP is below 50%, Treatment Effect +30%.

Xaihi's Skill Priority

From our experience, Xaihi is best played as a support unit that’s applying HP Treatment (Healing) and Cryo Infliction as often as possible. To this end we want to start with her Battle Skill Distributed DoS, which boosts her Arts Amp and Treatment scaling values. Next we go either with her Combo Skill or her Ultimate, both are good, and both work fine. Her Combo skill only gains additional damage multiplier, but it has a low cooldown and will be used very often. Meanwhile for utility, her Ultimate offers both Cryo and Nature base Amp increases, as well as scaling the maximum amp possible.

How to Play Xaihi

Xaihi is a Cryo Support Operator who specializes in HP Treatment (Healing) and can apply Cryo Infliction. Her Battle Skill Distributed DoS is central to her playstyle, summoning an Auxiliary Crystal that orbits the controlled operator. The crystal restores the Operator's HP when a Final Strike is performed on an, and triggering this effect at max HP grants an Arts Amp instead of restoring HP. After an Auxiliary Crystal has used up its HP Treatment charges, Xaihi can trigger her Combo Skill Stress Testing to launch the Crystal at enemies, dealing Cryo damage and Cryo Infliction.

This loop makes up a majority of Xaihi's gameplay, but in addition to the utility of the HP Treatment and Cryo Infliction, she also has the ability to Amplify Nature and Cryo damage through her Ultimate. The size of the Amp scales with Xaihi's Intellect stat. A very simple yet effective Battle Skill > Combo Skill > Ultimate rotation allows her to not only grant HP Treatment very reliably, but also majorly boost the Controlled Operator's Arts damage and the entire team's Cryo and nature damage. Truly a perfect Support.
