Yaoyao is a 4-star Dendro Polearm healer who deploys Yuegui, a bouncing radish that heals allies and deals Dendro DMG. Her Elemental Burst summons multiple Yueguis for massive team-wide healing. As one of the few Dendro healers in the game, Yaoyao is invaluable in Nilou Bloom teams where self-damage from Bountiful Cores requires constant healing. She also fits comfortably in Aggravate and Quicken teams, providing Dendro resonance and sustain. Despite being a 4-star, Yaoyao's combination of off-field Dendro application and team healing makes her a top-tier support.

1. Best Weapons (Ranked)

Bottom line: Favonius Lance provides team energy. Black Tassel R5 is a 3-star with massive HP% for healing. Kitain Cross Spear (craftable) provides EM and energy. Focus on HP and ER — damage stats are irrelevant.

5. Rotation Guide

Nilou Bloom rotation:
Nilou E×3 (Bountiful Core stance) → Nahida E+Q (mark + EM buff) → Yaoyao E (Yuegui, Dendro application) → Xingqiu E+Q (rain swords) → Yaoyao Q (team heal if needed) → Repeat

6. Common Mistakes

❌ Building DMG stats on Yaoyao — she's a pure healer. ATK/Dendro DMG/Crit do almost nothing. HP and Healing Bonus only.

❌ Not using Deepwood if no one else has it — 30% Dendro RES shred is essential for Dendro teams. Someone on the team MUST hold 4pc Deepwood.

❌ Using Q unnecessarily — Yaoyao's burst locks her on-field for 5 seconds. Only use when team is low HP. Her E heals enough normally.

❌ Not leveling E talent — Yuegui's healing scales with E talent level. Prioritize E over Q.
