The odds tier and the power tier line up almost exactly, which makes the maths simple: at 0.1% you
are looking at roughly 1,000 rerolls, or 5,000 Crystals, for a specific Mythical. The 2% Legendary
band is where most builds actually land, and Executioner at +25% damage and −10% cooldown is a
perfectly good stopping point.
Mythical traits — 0.1% roll chance

Azure Dragon
0.1%
+100% damage and -20% cooldown. Below 50% HP, damage rises by a further +75%; below 30% HP the skill can pierce a fish's invincibility.
White Tiger
0.1%
+50% critical hit rate and +100% critical damage. Each cast adds +5% critical rate, stacking to +30%.
Vermilion Bird
0.1%
-50% cooldown and +25% damage. Casting the skill resets its own cooldown once per match.
Black Tortoise
0.1%
+15% healing and +30% damage, and skills gain a stun. Below 20% HP you gain 20 seconds of invincibility.

Which trait for which skill
Raw damage: Berserk (+15%) is the accessible pick, Executioner (+25% and cooldown) the realistic ceiling, Azure Dragon the jackpot.
Crit builds: Sharp → Precision → Assassin → White Tiger, in that order of rarity. White Tiger is the only trait that stacks during a fight.
Cooldown: Swift 4%, Rapid 8%, Chrono 20% with damage attached, Vermilion Bird 50% plus a once-per-match reset.
Survival: Black Tortoise is the only trait that gives you invincibility, and it pairs specifically with the skills that hurt you — Ruinous Sacrifice drains 20 HP a second.
Two numbers that do not agree
Black Tortoise invincibility. The board's trait card still says 12 seconds. The
board's own update log for 7/11 says it was buffed from 12 to 20, and an August 29 gameplay guide
states 20. Treat 20 seconds as current and the card as stale.
Azure Dragon and Vermilion Bird. The board lists Azure Dragon at +100% damage with
the invincibility pierce below 30% HP; the August 29 guide says +150% and below 40%. The board lists
Vermilion Bird at +25% damage, the guide at +30%. Unconfirmed as of August 31, 2026 — both figures
are given here rather than one being picked.
