Guide🔗

Note: the following is NamuWiki community assessment (KR server), subjective community opinion, translated faithfully.

• A one-woman army who can do the work of three by herself. Fittingly for an Inner-Break character released on pickup right before Outer One, she came out with power strong enough to say the balance is completely broken; a broken-tier character who can single-handedly handle heal / DPS / tank / buff / debuff / status-cleanse together with her summons.
• Passively she summons a support drone that can heal + shield + cleanse debuffs + buff firepower + use an area debuff skill. Actively, if you just match the class, she can fire a 3x5 area skill every turn and summon a ranged DPS drone capable of sniping; she herself can pump out area firepower, debuffs, or support as she likes, active in both PVE and PVP.
• Unlike Gamma (a specialized enhanced version of Meri), she is not just a different character from the original Cordelia (a trap+buffer position), but is so insanely strong it becomes embarrassing to compare them.
• PVP: She is extremely strong and has lots of physical-penetration lines, so she shows firepower fully in PVP too. With just a little control you can dump her own and the artillery drone's two consecutive 3x5 area skills plus the support drone's silence in one turn; in Fighting Tournament, where opponents typically bunch up in a single column, if this combo lands the opponent may as well declare themselves dead. So opponents want to remove her as fast as possible, but she is a ranged attacker whose skills are summons or long-range and stay in the back row, so you must break through the drones and other characters to deal damage. All drones have 25% damage reduction, are immune to weaken/fear and ignore damage-over-time, so they don't crumble to formation-breaking, stun, or DoT; the support drone has heal + debuff-cleanse + shield, making other characters' durability higher too, so front-line breakthrough is hard. Even if you break through, with the passive Reinforced Armor Plate effect she is no glass cannon, and if she picked the "endgame-rated" Automata Tinker class she also gains attack-scaled def/res, gets another Reinforced Armor Plate when a drone dies, and has HP-recovery options stacked on the passive and high-awakening dedicated weapon, so her durability is excellent and she is extremely hard to kill.
• As a result, in the top-tier PvP meta of mid-to-late June 2026 (when Theta released), the so-called "Al-Gam-ja-Pong-Se" comp of Altair + Gamma + Zard + Frederick (Pongpong-i) + Theta dominates, chewing through even Outer One comps.

Recommended gear: dedicated weapon is a crossbow named "Nothing" (added stats: attack and physical penetration); its awakenings scale up strongly, with the 3rd awakening (TP-gain effects) being the key one, enabling the combo Artillery Drone Summon -> Lightning Burst -> extra turn -> Plasma Buster. For armor, prioritize sets that raise attack/HP/crit-rate (which transfer to summoned robots); best fit is Cirano's dedicated "Successor" set, with Salsu 2 (attack) plus Milsa 2 or Myeonggye 2 (HP), or Ilgi 2 for PVP. Accessory: Cirano's dedicated "Changse-birok"; otherwise Goyeongban for PvP or Necronomicon for PvE, and Whetstone if focusing firepower via Plasma Buster's added-hit Plasma Collapse.
