Xaihi Build: Gear, Weapon & Teams

Character Profile

Xaihi (full name Séraphine Xaihi) is a Supporter who heals and buffs the team through Amp effects, sent from Laterano to Talos-II by the Cabal of Tranquility for technical research. She now works aboard the Dijiang on information-engineering jobs such as building out the Protorig Network. Far more comfortable with machines than with people, she has a real gift for information technology, recognized even by the Abbess of the Great Monastery, though her habit of unauthorized upgrades has caused a few infrastructure mishaps.

Contingency Contract Fit

Test Criteria this kit handles well, since every criterion is a penalty or enemy buff and Xaihi sidesteps or shrugs these off. See the full dashboard for every modifier.

• Withering · She compresses team healing into one slot, so the squad stays topped up without the between-wave Healing Masses.
• Thrill · Tanky, ranged or well-healed, so the enemy damage spike is survivable.
• Toxic Residue · Ranged or self-sustaining, so the lingering toxin patches do little.
• Decapitate · Durable or ranged, so the extra damage on the active operator stays manageable.
• Hypoxia · Ranged or durable, so losing dodge and stamina hurts far less.
• Partition · Self-sufficient carry that does not need to swap operators mid-fight.
• Vitality · Sustained or amplified damage chews through the inflated HP pools.
• Weaken · Team buffs and a strong economy help offset the flat stat reduction.
• Whittle Down · Avoids or absorbs incoming damage, limiting the Max HP erosion.

Summons an Auxiliary Crystal that orbits the controlled operator for a while. After the controlled operator performs a Final Strike on the enemy, the Auxiliary Crystal will restore the said operator's HP. This effect can trigger 2 times. The attribute of Will increases the amount of HP treatment. When the controlled operator is already at Max HP when triggering the HP restoration, grant the said operator a temporary Arts Amp as well. This effect cannot stack.
