Quick Verdict: Luna is a Defender-class SSR with strong PvP and PvE utility. Base stats — HP 5635, ATK 757, DEF 661, SPD 103 — combined with Action Point generation and debuff-removal make her a genuinely versatile frontline pick. Worth pulling if you need a durable unit that disrupts enemy buffs and sustains team momentum. F2P players can run her at base constellation with solid results.

Who Is Luna?
Luna is a Defender-class SSR born July 16, standing 162 cm, voiced by Sam Slade. Her preferred gift is Machiavelli — relevant if you're focused on relationship progression. As a Defender, she anchors the frontline: absorbing pressure, generating Action Points, and enabling her team through barriers and debuff removal rather than raw damage.
Her core mechanic: AP generation on demand. She generates 5 AP at turn start and 35 AP every time she's hit. The more pressure enemies apply, the more resources she feeds back into your team's action economy. It's counterintuitive, but powerful — aggressive enemy AI actively works in your favor. She also provides a permanent 15% Defense increase, reinforcing her role as a damage sponge who converts incoming pressure into team advantage.
Luna's Full Skill Kit
Moonlight Slash (Normal Attack)
Weakness Gauge Reduction: 1 | Cooldown: None
On hit, 20% chance to trigger a Dual Attack from the ally with the highest ATK stat. If Luna is already executing an Additional Attack, that jumps to 50% (base 20% + 30% bonus).
Upgrade path:
+2: +10% damage, +1 Weakness Gauge damage
+3: +15% effect chance (Dual Attack proc rate up)
+4: +10% damage, +15% effect chance
+5: +10% damage, +20% effect chance
Priority: +3 and +5. Increasing the Dual Attack proc rate directly amplifies your highest-ATK ally's contribution every turn.
Hero's Emergence (Skill 1)
Cooldown: 3 turns
Removes 1 debuff from all allies and grants a 2-turn Barrier to the entire team simultaneously — one of the most efficient team-wide defensive tools in the current meta.
Upgrade path:
+2: −1 turn cooldown (now 2 turns — massive improvement)
+3: +1 additional debuff removed per cast
+4: +1 turn Barrier duration (now 3 turns)
+5: +30% All Ally Priority
+2 is mandatory. Dropping from 3 to 2 turns means Hero's Emergence is available nearly every other turn, fundamentally changing your debuff cleanse and barrier uptime. The +5 All Ally Priority spike is a significant late-game PvP investment worth planning toward.
Someday I Will Reach the Moon (Ultimate)
Weakness Gauge Reduction: 2 | Cooldown: 6 turns | Base Unbuffable chance: 70% for 3 turns
Unbuffable is one of the most disruptive debuffs in PvP — it prevents enemies from receiving any buffs for its duration, directly countering support-heavy teams.
Upgrade path:
+2: +10% damage, +1 Weakness Gauge damage
+3: +15% effect chance (Unbuffable lands more reliably)
+4: −1 turn cooldown (now 5 turns)
+5: +15% effect chance (Unbuffable reaches ~100% effective rate)
PvP priority: +3 and +5. Near-guaranteed Unbuffable is the difference between a disruptive ultimate and a game-changing one.
Chain Skills
Weakness Gauge Reduction: 3 | Recovers 25 Chain Points after attacking
Also grants a 1-turn Barrier proportional to Max Health during chain sequences. Each upgrade from +2 through +5 adds +5% Dual Attack Skill Chain damage, with additional Weakness Gauge damage at +2 and +5.
Best Luna Build
Artifact Recommendations
All pieces should be Level 5, Tier 4 for maximum efficiency.
Force Field Generator (HP% 48%, Solidity set) — Barrier equal to 20% Max Health for 2 turns on action; best for sustain builds
Talisman of Animosities (HP% 48%, Momentum set) — +10% Priority on single-target skills; improves turn order positioning
Chalice of Longing (SPD, Chill set) — 100% chance to gain +10% Priority when hit, once per turn; synergizes directly with Luna's get hit, gain resources identity
Unholy Exsultet (SPD, Encumbrance set) — Reduces entire enemy team's ATK by 15%; strong defensive utility
Coward's Treasure (HP%, Punishment set) — 30% chance to Counterattack when any ally is hit; adds offensive pressure without requiring Luna to act

Set Bonuses
Speed Set is the core recommendation:
2-piece: +13% Speed
4-piece: +12% Speed
Combined, this ensures Luna acts earlier in turn order — getting barriers and debuff clears out before enemies can capitalize.
Substat Priority
Speed → Health → Crit Chance → Accuracy → Attack
Speed is non-negotiable. Luna's AP generation loop and barrier timing depend on acting frequently. Health amplifies barrier values (several artifacts scale off Max Health). Crit Chance improves damage contribution. Accuracy ensures Unbuffable lands consistently in PvP.
Charm Recommendations
PvP: Vanguard's Charm (Level 5) — recovers 50 AP on multi-target hit at base, scaling to 60 AP at Level 10
PvE Option 1: Sage's Charm (Level 5) — generates 10 Chain Points on advantageous element attacks; Level 10 adds +1 Weakness Gauge damage to all-enemy attacks
PvE Option 2: Saint's Charm (Level 5) — generates 10 Chain Points on non-attack skills; Level 10 adds +1 Skill Chain Weakness Gauge damage
PvE and PvP Performance
PvE
Luna's PvE value is team sustain, not personal damage. Hero's Emergence keeps squishier DPS allies alive through multi-hit boss mechanics. Moonlight Slash's Dual Attack proc (up to 50% with Additional Attack active) effectively adds a free high-ATK ally action every other turn — that compounds over longer fights.
For raid content, her Weakness Gauge reduction across all three skills (1 from Moonlight Slash, 2 from ultimate, 3 from Chain) makes her a reliable shield-breaker. Her Water ally synergy bonuses — 70% Dual Attack Weakness Gauge damage and 30% Max Health increase for Water allies — make her especially effective in Water-element compositions.
PvP
Luna's PvP identity comes down to two mechanics: Unbuffable and AP generation under pressure. In Arena and Guild Wars, buff-stacking teams (ATK up, DEF up, Speed up) are directly countered by a well-timed ultimate. At +5, Unbuffable application reaches near-certainty — she becomes a genuine meta disruptor, not just a passive tank.
And the +5 Hero's Emergence upgrade adding +30% All Ally Priority is a late-game power spike that gives your entire team a turn-order advantage for two turns after each cast. Plan for it.
Skill Upgrade Priority
Hero's Emergence +2 — halves the cooldown; highest single-upgrade value in her kit
Moonlight Slash +3 — increases Dual Attack proc rate on every turn
Someday +3 — makes Unbuffable more reliable for PvP
Someday +4 — reduces ultimate cooldown to 5 turns
Hero's Emergence +5 — +30% All Ally Priority; significant late-game PvP investment
Someday +5 — near-guaranteed Unbuffable; essential for high-level PvP
Final Pull Verdict
Pull if:
You need a frontline Defender who generates team resources under pressure
Your roster lacks reliable debuff cleansing and barrier application
You face buff-stacking teams in PvP regularly
You run Water-element compositions and want the 70% Dual Attack Weakness Gauge damage bonus
Skip if:
You already have a high-investment Defender covering barrier and cleanse
You need a dedicated DPS carry — Luna doesn't fill that role
You're early in progression and lack Tier 4 artifacts to unlock her full potential
Wait if:
You're 10–20 pulls from pity on a banner addressing a more critical roster gap
You want to see whether upcoming balance patches adjust her ultimate cooldown or Unbuffable duration before committing
FAQ
Is Luna worth pulling in March 2026? Yes, for players who need a durable Defender with team utility. Her AP generation, barrier application, debuff removal, and Unbuffable ultimate make her one of the more versatile SSR Defenders in the current meta.
What's Luna's best build? 4-piece Speed Set with Chalice of Longing or Force Field Generator. Prioritize Speed, Health, and Crit Chance substats. Vanguard's Charm for PvP; Sage's or Saint's Charm for PvE.
Is Luna DPS, support, or tank? Defender — tank-adjacent with strong team utility. Not a primary DPS carry. Her value is barrier generation, debuff cleansing, AP feeding, and Unbuffable disruption.
Is she good for PvP? Yes, especially against buff-reliant teams. Her ultimate applies Unbuffable to all enemies for 3 turns at 70% base chance — near-guaranteed at +5 — directly countering support-heavy Arena and Guild Wars compositions.
Which upgrades are mandatory? Hero's Emergence +2 first — the cooldown reduction is the single most impactful upgrade in her kit. Then Moonlight Slash +3 for Dual Attack proc rate, followed by Someday +3 and +5 for reliable Unbuffable in PvP.
Is Luna viable for F2P players? Yes. Base constellation with a Speed Set and any available Tier 4 artifact performs well in story, dungeons, and casual PvP. The +5 Hero's Emergence upgrade is a long-term goal, not a prerequisite.
