B tier on patch 0.5.12
Player lists rate Yuuna between A and B, and some players called her busted in September, but runs with her are among the least successful overall and only middling on SSS difficulty. She plays in Crit Rush Assassins on The Collector.
Picked at rank B and locked for the run. The order weighs what each one does for this hero in the comps that win, not the ability on its own.
Tiers are reviewed by hand after each patch (latest: 0.5.12), weighing the runs players share, most of them in Red Rift, the comps that clear the high difficulties, current player tier lists and recent balance changes. All 25 heroes side by side are on the hero tier list.
Yuuna throws one shuriken per 40 Crit, up to ten, and always at the lowest-health enemy — she is the cleanup Assassin, best on boards where a fight has already been softened. Crit is not a damage stat for her so much as a volume stat: every 40 points is one more projectile.
Unspent Shards become shurikens for Yuuna. Shard Precision Prism gives every hero Crit equal to the Shards in bank, and Banked Presence, her rank A upgrade in Crit Rush Assassins, adds 1 more Crit per banked Shard to Assassins for Rush (10). Inside that window 40 Shards held are worth 80 Crit, two extra shurikens from Shuriken Shadow Strike, and every Shard spent between fights takes a little of that away.
The build takes her to rank S on The Collector: one extra shuriken per cast, plus 1d5 Shards on a kill once per combat, a payout that permanently grows by 1 each time. At rank S her Crit is 95 before items, 50 base and 15 per rank. Two Thief's Dagger add 22 Crit and 3 Shards per kill each, Siphoning Dagger adds 15 Crit and steals 1 Mana per auto attack, and Nimble Boots give 40 Attack Speed and 25 more for Rush (8). Critical Invigoration, her rank S upgrade, heals her for 50% of her Crit and gives 3 Mana on every Crit.
The Shadow gives her 4 seconds of Stealth when she falls below 75% Max HP, once per combat, and every time she gains Stealth she also gets 40 Mana and permanently gains 5 Crit plus 5 per rank. Rogue's Cowl adds more of those moments, with Stealth at the start of combat and every 20 seconds. Before a 0.5.7 fix, Burn and Poison did not count as damage taken, so the 75% trigger stayed silent against them; it now fires against the Demon and anything else that burns or poisons.
The Nightshade leans on Poison: every Assassin Crit inflicts 4 Poison plus 4 per rank, with Backup, and her shurikens gain +150% Crit against Poisoned enemies. The volley itself took its current shape in 0.5.3, which raised the cap from 8 shurikens to 10, lowered the cost from 50 Crit per shuriken to 40 and lifted The Shadow's Mana from 30 to 40.
A hero climbs C → B → A → S — 3 upgrades in all. Every stat rises at the same rate on every hero, with one exception: the primary stat of the class rises three to four times faster. For Yuuna that stat is Crit.
| Stats | Per rank | C → S |
|---|---|---|
| Health | +12.5% | +37.5% |
| Defence | +8 | +24 |
| Attack | +6 | +18 |
| Magic | +6 | +18 |
| Attack speed | +5 | +15 |
| Critprimary | +15 | +45 |
| Mana regen | +1 | +3 |
Health rises as a percentage of base health; every other stat is a flat addition. The specialization is chosen at rank B, and the class modifier pools open at A and S.
Leap into the air and throw 1 (+1 per 40 Crit) shurikens at the lowest-health enemy for 150 (+150% Attack, +150% Magic) damage each. Max Shurikens: 10
A hero unlocks one of these at rank B. The choice is locked for the run, and it decides which role the hero ends up playing.
When Yuuna goes below 75% Max HP, she gains Stealth for 4 seconds. Triggers once per combat. Whenever Yuuna gains Stealth, she gains 40 Mana and permanently gains 5 (+5 per Rank) Crit.
