(2) When a nearby party member triggers a Nightsoul Burst, the equipping character regenerates 6 Elemental Energy.
(4) After the equipping character triggers a reaction related to their Elemental Type, all nearby party members gain a 12% Elemental DMG Bonus for the Elemental Types involved in the elemental reaction for 15s. If the equipping character is in the Nightsoul's Blessing state when triggering this effect, all nearby party members gain an additional 28% Elemental DMG Bonus for the Elemental Types involved in the elemental reaction for 20s. The equipping character can trigger this effect while off-field, and the DMG bonus from Artifact Sets with the same name do not stack.
If no other member of the team can hold it, Scroll of the Hero of Cinder City (4) should be the top priority for Xilonen. The other options are there in the event someone else has Scroll occupied. If you do not need Xilonen's healing ability and are not using Peak Patrol Song, her artifact stats do not matter.
(2) Geo DMG Bonus +15%
(4) Upon obtaining an Elemental Shard created through a Crystallize Reaction, all party members gain 35% DMG Bonus for that particular element for 10s. Only one form of Elemental DMG Bonus can be gained in this manner at any one time.
(2) Elemental Burst DMG +20%
(4) Using an Elemental Burst increases all party members' ATK by 20% for 12s. This effect cannot stack.
(2) Increases Elemental Mastery by 80.
(4) Upon triggering an Elemental Reaction, increases all party members' Elemental Mastery by 120 for 8s.

Halcyon Years Unending
Gain "Ode to Flowers" after Normal or Plunging Attacks hit an opponent: DEF increases by 8~16% and gain a 10~20% All Elemental DMG Bonus for 6s. Max 2 stacks. Can trigger once per 0.1s. When this effect reaches 2 stacks or the 2nd stack's duration is refreshed, increase all nearby party members' All Elemental DMG Bonus by 8~16% for every 1,000 DEF the equipping character has, up to a maximum of 25.6~51.2%, for 15s.
The buff from this weapon caps out once Xilonen reaches 3,200 DEF.

Revolutionary Chorale
A part of the "Millennial Movement" that wanders amidst the winds. Increases DMG by 10~20%. When the character wielding this weapon triggers Elemental Reactions, they gain a Sigil of Rebellion. This effect can be triggered once every 0.5s and can be triggered even if said character is not on the field. When you possess 2 Sigils of Rebellion, all of them will be consumed and all nearby party members will obtain "Millennial Movement: Song of Resistance" for 12s. "Millennial Movement: Song of Resistance" increases Normal, Charged, and Plunging Attack DMG by 16~32% and increases ATK by 20~40%. Once this effect is triggered, you will not gain Sigils of Rebellion for 20s. Of the many effects of the "Millennial Movement," buffs of the same type will not stack.
This option is competitive with Peak Patrol Song if the team can utilize both of its buffs. To proc it consistently, you either need to burst every rotation, or add a delay between the initial skill hit and normal attacking. It is not needed to level this weapon for Xilonen.
