Revision 1

These builds apply inside 999 Nights, where Esper Zero, Mint, Iroi and Shinku use Warren equipment. The four builds form one White Lightflame setup: Zero supplies application, Mint raises the debuff payoff, Iroi shares buffs and stacks, and Shinku takes the main damage window. Later equipment supports other setups.

Esper Zero: application and transitions

Morningstar Longsword converts the wearer's Crimson Flame into White Lightflame, shortens the allied trigger interval by 50%, extends Crimson Flame by 10 seconds and gives the wearer's attacks a 50% application chance. Flamesong combines Whiteflame Ballad and Flame of Dawn to help passive application and party transitions. After Iroi and Mint set up, use Zero to build Charge and continue the rotation toward Iroi and Shinku.

Mint: raise the stack payoff

Sunsinge Twinblades combines Lightflame Judgment and Dragonflame Kindling. It converts the wearer's Crimson Flame, increases the damage taken by a target for its White Lightflame stacks and raises the Dragonflame stack limit. Ultimate and charged Basic Attacks apply Dragonflame. Radiant armor combines Sunseeker Light and Sunward Windrider. Bring Mint in after Iroi to establish the stack and damage effects, then refresh them between the other party members' turns.

Iroi: group and prepare

Flamecrown Codex doubles the number of White Lightflame stacks applied by allies. Its Scorchfire Rebirth converts allied Crimson Flame and Monster Burn into HP recovery and applies Crimson Flame to allies and the target when Iroi casts Ultimate. Lightchant armor combines Shared Emberdream and Dragonflame Suite for shared effects and recovery against affected enemies.

Use Iroi to gather enemies, then have Zero and Mint apply their effects. Return to Iroi to synchronize the stacks before giving Shinku the damage window. Fuzzy Charm supplies allies a 12-second shield equal to 50% of the wearer's Max HP on Ultimate. Family Portrait raises allied damage by 20% per full-HP ally and lowers it by 20% per fallen ally; its team effect does not stack.

Shinku: spend the setup

Radiant Sun changes the relevant Ultimate application to White Lightflame and restores three Defiant Spirit when Shinku attacks a Crimson Flame target. After the other three characters prepare the field, transform with Ultimate and alternate attacks with Scarlet Descent as the resource allows. Starfall body and leg armor with Cloudbreaker pauldrons and boots supplies two armor effects while completing Dragon and Dragonhunter.

Accessories and tradeoffs

Secret Syrup adds splash damage at a 25% ratio when the wearer damages a target, with a 0.25-second cooldown. Tempering Stone raises allied damage by 80% but also reduces allied DEF by 80%, making it a substantial survival tradeoff. These are useful offensive options for Zero or Mint. Cloudrider Charm halves Stamina cost with a non-stacking team limit and is a mobility option for Shinku.
