How to play
Decision notes for shops and formation — not a copy of the in-game panel.
Early
Pair with a damage partner who softens packs. Crit tools matter immediately. She is a finisher, not wave one tank.
Mid
Shadow = HP threshold Stealth once per combat + permanent scaling on Stealth. Collector = extra shuriken and kill Shard growth. Nightshade = +Crit vs Poisoned and Assassin Crit spreads Poison. Pick personal Stealth, Shard snowball, or Poison tribal.
Late
Assassin Ambush/Smokescreen and Crit relics. Keep feeding low-HP targets so the leap always has a job.
Positioning
Mid-back so the leap reaches the collapsing target without eating the first volley.

Abilities

activeLeap into the air and throw 1.23 (+ 150% Crit ) shurikens at the lowest-health enemy for 0 (+ 150% Attack , + 150% Magic ) damage each. Max Shurikens: 1
In practice: Lowest-HP targeting is automatic triage. Soften first — full-HP casts feel weak even with good Crit.

Best relics & synergies
Relics that overlap Assassin keywords and Yuuna's ability tags. Top matches include a short “why”.
Assassin's Ambush Engine
Heroes gain 30 Crit. Whenever an Assassin auto attacks while Stealthed, they inflict Poison on their target equal to 30% of their Crit. At start of combat, Assassins in the back 1 rows gain Stealth for 1 seconds and target the most threatening enemy.
Why: Execute engine for lowest-HP leaps.
Assassin's Supremacy Filigree
For Rush (1), Assassins gain Stealth and 200 Crit.
Why: Crit supremacy for shuriken counts.
Assassin's Elevation Prism
Whenever an Assassin kills an enemy they permanently gain 1 Crit then you gain 0 Shard per 0 Crit they have (Max: 1).
Why: Matches Yuuna's Assassin / Crit / Shard tags.
Assassin's Emblem
If there is an Assassin in combat, Heroes gain Stealth for 1 seconds the first time they go below 3% Max HP each combat.
Assassin's Smokescreen Banner
Assassins gain Stealth for 1 seconds the first time they go below 100% Max HP each combat.
Why: Stealth/smoke fantasy matching Shadow.

FAQ
Common questions when this hero shows up in the shop or draft.
Is Yuuna good in Guildrun?
High ceiling finisher with Crit/Poison support. Poor as a solo early board. Buy her to clean up, not to open.
What class is Yuuna?
Assassin. Role focus: Crit shuriken leap onto the lowest-health enemy.
What relics work with Yuuna?
Assassin Smokescreen/Ambush/Supremacy pieces and Crit/Poison enablers.
How do you play Yuuna?
Soften packs, stack Crit, cast Shadow Strike on collapsing targets, and pick Shadow, Collector, or Nightshade based on Stealth, Shards, or Poison.
Tips
- If she leaps and dies, you needed Stealth timing or a tank — not only more Attack.
- Nightshade without Poison on the board is a weak Crit branch; apply Poison first.
