Altair

The reviewer is openly unhappy about Altair. He plays for the Genesis War cast, not the collaborations, and thinks a collab unit this strong is an Outer One in all but label — strong enough that he knows people quitting over facing her. (30:02)

His practical advice is the exact opposite of a warning, though. Everyone was given three copies free, three copies are genuinely enough, and full manifestation is a waste of resources. (1:33)

Read the passive sheet before you spend

Most of her passive lines carry no number after the name, and he walks through what that means: no number, no change with rank. What actually improves is Ancient Wisdom's cooldown — 3 turns at 3 copies, 2 at 6, and finally 1 at 4 manifestations, which is the point where she plays like the full version. His verdict is blunt: full manifestation is overkill, and the free copies are fine.

Spatial Distortion scales off the attacker's Crit

It works like Veramode's dimensional field, but where Veramode keys off his own Crit Rate, hers is computed from the attacker's Crit Rate against her Crit-Rate-taken reduction. The higher the attacker's Crit, the more often she shrugs the hit off entirely. He flags this as his own reading rather than anything official. (2:05)

Apocalypse Distortion is a better revive than Esmeralda's

Same idea, but it lasts only a turn, so she comes back faster. And the heal and debuff clear on waking are already there at 3 copies, where Esmeralda needs full awakening for the equivalent. (3:38)

Class: Dark Oracle over Aurelion

He started on Aurelion and switched. Aurelion's healing rider needs an area skill, and her area skills are already heals, so it adds very little.

Dark Oracle brings Crit Rate — which matters because Black Mirror's reflect can crit — applies a Weaken and strips two buffs on attack, and tops Spatial Distortion back up at end of turn. That last part is why even a 3-copy Altair holds her stacks, as long as she isn't being hit. Worth knowing that our own class notes further up this page don't have Dark Oracle's text captured from the client yet; this section is the gap-filler. (7:48)

Moirai is absurd for 1 TP

One TP, two-turn cooldown: a heal, two debuffs removed, +1 TP, and Vitality Tune on top (+20% ATK/M-ATK, +20% healing received, all Action Control cleared, 40% of M-ATK healed at end of turn). Equipping Moirai is also what switches on Fate Interference, which is where the Authority buffs come from. (9:54)

One quirk in that system: Fate Interference can only be placed on a non-Outer-One, non-collab ally with no death prevention — but when the carrier of Cycle of Fate dies and it moves to someone else, none of those restrictions apply to the new holder. An Outer One can end up with it. (11:28)

Arcane Circle copies buffs across the whole group

Heal, two debuffs cleared, Mana Unleash — and then it takes every removable buff off allies in range and copies it to all of them with +1 turn duration. Joan Kartright's Lightning Blade, weapon-granted M-ATK buffs, opening shields: anything not flagged unremovable gets duplicated to everyone.

It also cuts normal-skill cooldowns by 1 on the recipients, not on Altair. His one correction to his own reading: "all allies" means allies inside the 3-tile area, not the whole team. (14:01)

Black Mirror ignores damage reduction

A shield worth 50% of M-ATK that reflects 80% of M-ATK when she is attacked, boosted further by shield-increase effects, and it can crit. The key line is that it ignores damage-taken reduction — so Dragon Slayer Zephyr and Black Prince, whose entire defence is stacked reduction, take it in full. Reflect caps at three triggers per turn (80% + 25% + 25% = 130%). (18:08)

Skills and the ultimate

Moirai, Arcane Circle and Black Mirror is the fixed loadout; there is no reason to slot anything else. The ultimate needs 5 TP and, because she is spending TP constantly on buffs, she rarely gets there — despite the weapon keeping her topped up. (21:11)

Gear

HP on head and boots, M-ATK on the rest. Accessory is Stopwatch: its 15% Crit-Rate-taken reduction feeds Spatial Distortion directly, and the cooldown reduction matters because she casts every single turn. (22:44)

Weapon: ★3 is the breakpoint, then ★5 and ★6

★1 does effectively nothing. ★2 adds Range +1. ★3 refills TP when she is at 1 or below, once per turn; ★4 removes the once-per-turn limit; ★5 adds Veramode-style debuff shedding when attacked; ★6 raises the trigger to TP 2 or below, at which point her TP simply never runs out. His shortlist is 3, 5, 6 — and ★3 alone is enough to play her. (23:47)

Runes

Slots 4 and 5 take Mercy runes for the healing increase and never change. Devotion runes in 3, 2 and 6 are the upgrade — slot 6's shield increase feeds straight into Black Mirror's reflect damage. (26:24)

Artifact: Mage Crystal, nothing else

Magic Resonance Stone and Peak Condition+12 more → both go unused.

Mage Crystal's shield-granted bonus pushes Black Mirror's reflect past 100% of M-ATK, and Medea's Magic turns her basic attack into Dark Hand: 100% M-ATK, steals TP, heals her for 50% of damage dealt, and applies Ghost — which restacks every time the target is attacked, so a focused target ends up at -50% ATK/M-ATK and +50% damage taken.
