Master Xilonen's abilities and understand her core mechanics
Xilonen's kit revolves around her Elemental Skill (Yohual's Scratch), which allows her to enter the Nightsoul's Blessing state. In this state, she gains Source Samples that convert based on your team's elemental composition, enabling her to provide elemental resistance shred for Hydro, Pyro, Cryo, and Electro allies.
Normal Attack: Performs up to 4 rapid strikes.
Charged Attack: Consumes Stamina to unleash 2 rapid sword strikes.
Plunging Attack: Plunges from mid-air to strike the ground, damaging opponents along the path and dealing AoE DMG upon impact.
Xilonen enters the Nightsoul's Blessing state and gains 3 Source Samples (initially Geo element). Depending on your party members' elements (Hydro/Pyro/Cryo/Electro), these samples convert to match those elements.
Key Mechanic: When Xilonen's Nightsoul points are full (gained via Normal Attacks in Nightsoul state), she triggers Elemental RES Shred against nearby enemies for the corresponding elements.
Nightsoul's Blessing State:
💡 Pro Tip: The resistance shred scales with DEF. At 2000 DEF, you get ~20% RES shred. At 3000+ DEF, you reach the maximum 33% RES shred.
Xilonen summons her Ocelot spirit to deal AoE Geo DMG based on her DEF. The effect changes based on the number of converted Source Samples:
Support Mode (≥2 Converted Samples):
DMG Mode (<2 Converted Samples):
⚠️ Important: Xilonen requires 60 Energy for her burst. With her Skill generating particles and potential Favonius weapon, aim for 180-200% Energy Recharge for consistent uptime.
When Xilonen triggers Shattered Nightgleam (max Nightsoul points), all nearby party members gain 10% increased Elemental DMG Bonus for the corresponding element of the converted Source Samples for 15s.
Effect: This provides a team-wide damage buff that stacks with the resistance shred, making Xilonen an even more powerful support.
Increases the Level of Yohual's Scratch by 3. Maximum upgrade level is 15.
Additionally, when Xilonen is in the Nightsoul's Blessing state, her resistance to interruption is increased.
When Xilonen is in the party, she grants the Nightsoul's Blessing state to all party members, allowing them to interact with certain Natlan mechanisms.
Exploration Use: This is crucial for exploring Natlan, as it allows your entire team to use Nightsoul mechanics without Xilonen needing to be on the field.
After using Yohual's Scratch, Xilonen's DEF is increased by 20% for 15s. Additionally, the duration of Nightsoul's Blessing is extended by 3s.
Value: Nice QoL improvement. The DEF boost helps with both healing and resistance shred. Extension allows more time to trigger RES shred.
When Xilonen triggers Shattered Nightgleam, all nearby party members gain 20% increased DEF for 12s. Additionally, the Elemental RES decrease effect is increased by an additional 6% (from 33% to 39%).
💎 High Value: This is Xilonen's best constellation. The extra 6% RES shred is significant, and the DEF buff helps the entire team.
Increases the Level of Ocelotlicue Point! by 3. Maximum upgrade level is 15.
When Xilonen's Burst is in Support Mode, the healing frequency is increased by 20%. When in DMG Mode, the additional Geo DMG is increased by 40%.
Increases the Level of Yohual's Scratch by 3. Maximum upgrade level is 15.
When Xilonen triggers Shattered Nightgleam, she deals 400% of her DEF as AoE Geo DMG to nearby opponents. This effect can occur once every 3s.
Value: Adds personal damage to Xilonen. With high DEF (3000+), this deals ~12,000 damage every 3 seconds. Nice for sub-DPS builds, but not essential for pure support.
📊 Constellation Value Ranking:
S-Tier (Best): C2 - Best overall value
A-Tier (Good): C1, C6 - Nice improvements
B-Tier (Okay): C3, C4, C5 - Skill levels and minor boosts
Verdict: C0 is complete. C2 is the sweet spot for investment.
Recommended Levels:
Q: How does the resistance shred work?
A: When Xilonen maxes her Nightsoul points in her Skill state, she automatically applies RES shred to nearby enemies. The shred amount scales with her DEF, maxing at 33% (39% with C2).
Q: Does she need to be on-field to maintain RES shred?
A: No! Once triggered, the RES shred effect lasts for the duration and applies to enemies near her, even if you swap to another character.
Q: Can she shred Geo RES?
A: No. Xilonen can only shred Hydro, Pyro, Cryo, and Electro RES based on your team's converted Source Samples.
Q: How do I get Support Mode vs DMG Mode on her Burst?
A: It depends on your converted Source Samples. With 2+ converted samples (non-Geo), you get Support Mode (healing). With fewer than 2, you get DMG Mode.
