The Knave of the Fatui

Arlecchino is a 5-Star Pyro Polearm user who functions as a high-risk, high-reward Main DPS. Her kit revolves entirely around the Bond of Life mechanic, which prevents her from being healed by external sources during combat but significantly boosts her Normal Attack damage.

Key Mechanics

• Bond of Life (BoL): Arlecchino gains BoL through her Skill and Burst. When her BoL is above 30% of her Max HP, she enters the 'Masque of the Red Death' state.
• Masque of the Red Death: Converts her Normal, Charged, and Plunging Attacks to Pyro DMG (cannot be overridden). It also boosts her damage based on her current BoL percentage.
• Self-Sustain Only: Her passive talent prevents her from receiving healing from teammates (like Bennett or Kokomi) while in combat. She can only heal herself using her Elemental Burst.

5-Star Options

• Crimson Moon's Semblance (Best-in-Slot): Tailor-made for her. It transforms into a scythe and provides a massive Bond of Life boost, along with high Base ATK (674) and CRIT Rate.
• Staff of Homa: An excellent stat stick providing huge CRIT DMG. Since Arlecchino often plays at varying HP levels and cannot be healed easily, the HP-to-ATK conversion is valuable.
• Primordial Jade Winged-Spear: A solid generalist option offering CRIT Rate and stacking ATK buff.

4-Star & F2P Options

• Deathmatch (Battle Pass): Great for balancing CRIT Rate causing consistent damage output.
• White Tassel (3-Star F2P): surprisingly competitive! Its R5 passive boosts Normal Attack DMG by 48%, which is Arlecchino's main damage source. Ideally used with Bennett to compensate for low Base ATK.

Best Sets

1. Fragment of Harmonic Whimsy (4-Piece): The dedicated set for Bond of Life users. It gives +18% ATK and a massive 54% DMG Bonus when BoL fluctuates.
2. Gladiator's Finale (4-Piece): A strong runner-up, offering +35% Normal Attack DMG. Easier to farm or Strongbox.
3. Crimson Witch of Flames (4-Piece): Best for Vaporize reaction teams.

Stat Priority

• Sands: ATK%
• Goblet: Pyro DMG Bonus
• Circlet: CRIT Rate or CRIT DMG (aim for 1:2 ratio)
• Substats: CRIT > ATK% > Elemental Mastery > Energy Recharge.

Vaporize Hypercarry

The standard high-damage setup leveraging Yelan or Xingqiu for consistent vapes.

• Core: Arlecchino + Yelan/Xingqiu + Bennett + Zhongli/Kazuha
• Strategy: Bennett buffs ATK (but won't heal Arlecchino), Zongli provides the shred and shield necessary for her survival as she cannot be healed.

Overload (Chevreuse)

A niche but powerful team taking advantage of Chevreuse's Pyro/Electro shred.

• Core: Arlecchino + Chevreuse + Fischl/Yae Miko + Thoma/Dehya
• Strategy: Constant Overload triggers allow Chevreuse to shred resistances. Strong AoE potential.
