SILVERPALACE BUILD

Rex Build

Updated 27 October 2026

Rex is a Fulmen Resonance DPS: build him for Amplitude Coefficient above 50%, then Amplitude Multiplier, with To Serve and Protect Implements and the Bloodline Feud Epiphany. Grimm is his best partner. Beta data.

Best Implements for Rex

To Serve and Protect

Best

Amplitude Multiplier +42% (4 pieces). Increases the holder's Amplitude Multiplier by 42%. When the holder's Amplitude Coefficient exceeds 50%, they also gain Thunderous Fury, further increasing their Amplitude Multiplier by 42%.

  • Defender of Justice, To Serve and Protect Head ImplementDefender of JusticeHead
  • Upholder of Order, To Serve and Protect Neck ImplementUpholder of OrderNeck
  • Crusher of Evil, To Serve and Protect Secondary Weapon ImplementCrusher of EvilSecondary Weapon
  • Eradicator of the Lawless, To Serve and Protect Accessory ImplementEradicator of the LawlessAccessory

Why: Righteous Spirit gives each Fulmen Resonance Effect 2 more damage instances, and this set's Amplitude Multiplier, up to 84% past 50% Amplitude Coefficient, boosts every one of them.

Illusion of Life

Alternative

Amplitude Coefficient +15% (4 pieces). Increases the holder's Amplitude Coefficient by 15%. When the character's Amplitude Coefficient exceeds 50%, each Skill use also increases their ATK by 8% for 8s, stacking up to 2 times.

  • Swirling Thoughts, Illusion of Life Head ImplementSwirling ThoughtsHead
  • Journey of the Argent Strand, Illusion of Life Neck ImplementJourney of the Argent StrandNeck
  • Time Cycle, Illusion of Life Secondary Weapon ImplementTime CycleSecondary Weapon
  • Conscious Echoes, Illusion of Life Accessory ImplementConscious EchoesAccessory

Why: Its 15% Amplitude Coefficient helps Rex clear the 50% line his main set needs, and his frequent Skill casts keep its ATK stacks up.

City Grime Alliance

Alternative

The holder grants an 8% DMG increase to all characters on the team who share the same Reactor Attribute.

  • Individual Struggles, City Grime Alliance Head ImplementIndividual StrugglesHead
  • At Home in the Storm, City Grime Alliance Neck ImplementAt Home in the StormNeck
  • Rousing Fanfare, City Grime Alliance Secondary Weapon ImplementRousing FanfareSecondary Weapon
  • Breaking Stories, City Grime Alliance Accessory ImplementBreaking StoriesAccessory

Why: Only worth it in a full Fulmen team, where every teammate who shares Rex's attribute gets 8% DMG.

Implement stats are fixed, not rolled. Set data is fan-compiled from the game files; where each set drops is in the Implements guide.

Best Epiphany for Rex

Bloodline Feud Epiphany

Bloodline Feud

Best

DMG Bonus +19.5%

Increases the holder's Amplitude Coefficient by 15%. When their Amplitude Coefficient exceeds 50%, each 1% over 50% grants 2.5% Amplitude Multiplier, up to a maximum of 125%.

Why: Every point of Amplitude Coefficient past 50% becomes 2.5% Amplitude Multiplier, up to 125%, the stat behind the extra hits his Passive adds.

The Fall of the House of Rot Epiphany

The Fall of the House of Rot

Alternative

DMG Bonus +15%

Increases the holder's Amplitude Coefficient by 15%. When their Amplitude Coefficient exceeds 50%, each 1% over 50% grants 0.8% ATK, up to a maximum of 40%.

Why: The Lv. 40 version of that clause, paying up to 40% ATK, to hold Rex over until Bloodline Feud drops.

Vengeance From the Void Epiphany

Vengeance From the Void

Alternative

DMG Bonus +18%

Increases the holder's ATK by 24% and grants Thunderclap. Thunderclap increases DMG as follows: for every 10 HP lost, DMG is increased by 0.022% up to a maximum of 22%; during Thunderous Fury, Thunderclap's DMG increase is calculated based on Max HP up to a maximum of 22%.

Why: Needs all four To Serve and Protect pieces, whose Thunderous Fury lets Thunderclap read Max HP for 24% ATK and up to 22% DMG; Bloodline Feud still pays more.

The Epiphany is the fifth gear slot, one per character. Duplicates raise its stats, never its effect. Effects are fan-compiled from the game files.

Rex stats

Rex's numbers revolve around one threshold: 50% Amplitude Coefficient. To Serve and Protect doubles its Amplitude Multiplier past it, and both Bloodline Feud and The Fall of the House of Rot only convert above it, so reach 50% first, using Illusion of Life's 15% if needed. After that, Amplitude Multiplier is the damage stat, since Resonance Effects scale on Amplitude and not on CRIT. See our character stats guide for the difference.

  5. 5Righteous Spirit, Rex's PassivePassiveRighteous SpiritOne levelRighteous Spirit: ATK stacks, extra resonance hits

Our order, not a creator's. Adaptive Rule goes first because it holds the Signature Moves that stack Righteous Spirit's 7% ATK. Thunderous Judgement is next: on top of its damage it hands back 120 Rage, a full bar, so the Skill loop starts again at once.

What every level costs is on the Rex materials page.

Rex Psyches

  1. Psyche IIron Superintendent. Upon using Tactical Assault, Rex gains 1 Volt Charge. Dealing DMG increases his Fulmen DMG by 2% for 8s, stacking up to 4 times.
  2. Psyche IINaval Governance. Increases Rex's Final DMG by 4%. After using Skill: Dual Truncheons and Skill: Extended Truncheon, he recovers the Rage consumed. This effect can only trigger once every 10s.
  3. Psyche IIIDarkened White. Upon gaining Rage, Rex's ATK is increased by 2.5% for 8s, stacking up to 4 times.
  4. Psyche IVRighteous Clause. Upon using Skill: Dual Truncheons, Skill: Extended Truncheon, or his Tactical Assault, Rex gains 1 stack of Ruthless Law. Each stack increases his Amplitude Multiplier by 10% for 20s, stacking up to 2 times.
  5. Psyche VModel Enforcer. Upon using Skill: Nunchucks Law, the Amplitude Coefficient of all characters on the team is increased by 25% for 60s.
  6. Psyche VIEvil Eradicator. Increases Rex's Final DMG by 6%. Whenever Rex casts Skill: Nunchucks Law, he deals an additional 100% Fulmen DMG, and his Fulmen Resonance increases by 100.

Each Psyche costs one more copy of Rex. Effects are fan-compiled from the game files. Our reading: Psyche V, Model Enforcer, matters most, because +25% Amplitude Coefficient for the whole team for 60s carries Rex past the 50% mark his set and Epiphany both need. The character progression guide explains the system.
