WHERE IT FITS

Characters and equipment that use this material

Passerby of Wandering CloudCavern relics★★★★★

Passerby of Wandering Cloud

Introduced in v1.0A four-piece Relic set for characters whose role benefits from increased outgoing healing and a Skill Point at battle start.Guide

Passerby of Wandering Cloud grants 10% Outgoing Healing with two pieces. Its four-piece bonus immediately regenerates 1 Skill Point at the start of battle. Consider it for a healer when stronger healing is useful, or when the opening Skill Point helps the party begin combat with more flexibility.

Pioneer Diver of Dead WatersCavern relics★★★★★

Pioneer Diver of Dead Waters

Introduced in v2.0Debuff-conditioned damage relic setGuide

Pioneer Diver of Dead Waters increases damage against debuffed enemies by 12% with two pieces. Four pieces add 4% CRIT Rate, plus CRIT DMG against enemies with at least 2 or 3 debuffs; after the wearer inflicts a debuff, the described four-piece effects double for 1 turn. Consider it for a damage dealer who attacks debuffed targets and can personally inflict debuffs to trigger the short-lived increase.

Iron Cavalry Against the ScourgeCavern relics★★★★★

Iron Cavalry Against the Scourge

Introduced in v2.3Break and Super Break damage relic setGuide

Iron Cavalry Against the Scourge gives 16% Break Effect with two pieces. With four pieces, it adds DEF ignore to Break DMG at 150% wearer Break Effect and additional DEF ignore to Super Break DMG at 250%. Consider it for a build that can meet those thresholds and deal the corresponding damage types; the thresholds are separate and the additional bonus applies specifically to Super Break DMG.

Warrior Goddess of Sun and ThunderCavern relics★★★★★

Warrior Goddess of Sun and Thunder

Introduced in v3.3Healing-triggered team support relic setGuide

Warrior Goddess of Sun and Thunder gives its wearer 6% SPD with two pieces. Its four-piece bonus activates when the wearer or their memosprite heals an ally other than the wearer, granting the wearer Gentle Rain for 2 turns. While active, the wearer gains another 6% SPD and all allies gain 15% CRIT DMG. Consider it for a wearer who can trigger that healing condition regularly.

Celestial DifferentiatorPlanar ornaments★★★★★

Celestial Differentiator

Introduced in v1.0A two-piece Planar Ornament set that raises CRIT DMG and can provide a large temporary CRIT Rate increase for the wearer's first attack. Consider it when the wearer has at least 120% current CRIT DMG and can make that opening attack matter.Guide

Celestial Differentiator grants 16% CRIT DMG. If the wearer's current CRIT DMG is at least 120%, entering battle grants 60% CRIT Rate until the end of their first attack. The set's distinctive payoff is therefore limited to that first attack, rather than being a lasting CRIT Rate bonus.

Inert SalsottoPlanar ornaments★★★★★

Inert Salsotto

Introduced in v1.0A two-piece Planar Ornament set that adds CRIT Rate and boosts Ultimate and Follow-Up ATK damage once the wearer reaches 50% current CRIT Rate. Consider it for wearers who use those attack types and can meet the threshold.Guide

Inert Salsotto gives 8% CRIT Rate. At 50% current CRIT Rate or higher, it also increases damage from the wearer's Ultimate and Follow-Up ATK by 15%. The threshold and attack types determine whether the second part contributes to a build.

Talia: Kingdom of BanditryPlanar ornaments★★★★★

Talia: Kingdom of Banditry

Introduced in v1.0A two-piece Planar Ornament set that increases Break Effect, with an additional increase at 145 SPD. Consider it for a wearer whose build makes use of Break Effect and can reach that speed threshold.Guide

Talia: Kingdom of Banditry gives 16% Break Effect. At 145 SPD or higher, it adds another 20% Break Effect. The higher bonus depends on meeting the SPD condition; the base Break Effect increase applies regardless.

Sprightly VonwacqPlanar ornaments★★★★★

Sprightly Vonwacq

Introduced in v1.0A two-piece Planar Ornament set that increases Energy Regeneration Rate and can advance the wearer's action at battle start. Consider it when the wearer values the regeneration and reaches 120 SPD for the opening advance.Guide

Sprightly Vonwacq grants 5% Energy Regeneration Rate. At 120 SPD or higher, it advances the wearer's action by 40% immediately upon entering battle. Its opening action effect is conditional on SPD, while the regeneration increase is not.

Penacony, Land of the DreamsPlanar ornaments★★★★★

Penacony, Land of the Dreams

Introduced in v1.5A two-piece Planar Ornament set that adds Energy Regeneration Rate and boosts damage for the wearer's other allies who share the wearer's Type. Consider it when the wearer and at least one other ally share a Type and can benefit from the damage bonus.Guide

Penacony, Land of the Dreams grants the wearer 5% Energy Regeneration Rate. It also increases damage by 10% for all other allies that are the same Type as the wearer. The damage bonus excludes the wearer, so its value depends on allies sharing the wearer's Type.

Sigonia, the Unclaimed DesolationPlanar ornaments★★★★★

Sigonia, the Unclaimed Desolation

Introduced in v2.1A two-piece Planar Ornament set that builds CRIT DMG stacks as enemies are defeated. Consider it in encounters where the wearer can trigger multiple enemy defeats and benefit from ramping CRIT DMG.Guide

Sigonia, the Unclaimed Desolation grants 4% CRIT Rate. Each time an enemy target is defeated, the wearer's CRIT DMG increases by 4%, stacking up to 10 times. Its CRIT DMG component therefore builds over enemy defeats rather than being fully active from the start.

Izumo Gensei and Takama Divine RealmPlanar ornaments★★★★★

Izumo Gensei and Takama Divine Realm

Introduced in v2.1A two-piece Planar Ornament set that grants ATK and can add CRIT Rate when a teammate follows the same Path as the wearer. Consider it when that team condition is met and the wearer benefits from both stats.Guide

Izumo Gensei and Takama Divine Realm increases the wearer's ATK by 12%. Upon entering battle, if at least one teammate follows the same Path as the wearer, the wearer gains 12% CRIT Rate. The CRIT Rate effect depends on a teammate's Path, not merely on the wearer having a particular Path.
