To use Water Hacker (Cynthia) as an Arena cleave damage dealer in Summoners War, build her on a high-damage Rage rune set and pair her with an Arena 44% Attack Power leader. While Hackers often fill utility roles, Cynthia's survivability mechanics allow her to cast her area-of-effect Skill 2 up to three times during an engagement if she takes an active turn before taking fatal damage.
Core Cleave Mechanics
Cynthia's offensive potential relies on the interaction between her Skill 2 burst damage and her survival mechanic. When built for maximum Attack and Critical Damage:
- Initial Strike: Moving early allows Cynthia to cast Skill 2 immediately, stripping enemy shields and chunking bulky targets.
- Passive Trigger: When opposing defenses retaliate with lethal damage, Cynthia's survival mechanic keeps her active and resets or preserves her offensive output.
- Multi-Cast Potential: In prolonged or reactive exchanges, Cynthia can fire Skill 2 up to three separate times, overwhelming high-HP stall defenses that survive the first hit.
- Leader Synergy: While Cynthia carries a native Speed leader skill, substituting a 44% Arena Attack Power leader maximizes her raw damage multipliers, pushing her burst above stall thresholds.
Rune Sets and Target Benchmarks
Equip Cynthia with a four-piece Rage set to maximize Critical Damage. Pair it with Will to protect against outspeeding crowd control, or Blade if you need extra Critical Rate to hit consistency caps.
| Rune Slot | Primary Stat | Desired Substats | Target Benchmark |
|---|---|---|---|
| Slot 2 | Speed or ATK% | SPD, CR, CD, ATK% | +90 to +120 Bonus SPD |
| Slot 4 | Critical Damage | CR, SPD, ATK%, HP% | 180% to 220%+ Crit DMG |
| Slot 6 | ATK% | SPD, CR, CD, ACC | +1,400 to +1,800 ATK |
| Overall | — | — | 85% to 100% Crit Rate |
Artifact Substats
Focus both Water Attribute and Type artifacts on properties that amplify Skill 2 output and flat scaling:
- Skill 2 Critical Damage: Directly scales her primary cleave ability.
- Critical Damage as Enemy HP is High / Low: Enhances opening burst and execution thresholds on weakened targets.
- Damage Dealt on Fire/Water: Increases offensive pressure against meta defense elements.
- Added Damage by ATK/SPD: Adds flat supplementary damage to cut through high-defense units.
Team Composition and Turn Order
A Cynthia cleave offense requires dedicated buff stripping, attack bar pushing, and an area-of-effect Defense Break to set up her damage window.
Recommended Team Roles
- 44% Arena Attack Leader: Alicia, Brandia, or Raki. Alicia can also act as a secondary cleaner if targets survive.
- Stripper / Booster: Tiana or Chiwu dispels enemy Will runes and pushes your attack bars forward.
- Buffer / Defense Breaker: Galleon provides a 2-turn Attack Buff and an AoE Defense Break via Time to Loot.
- Primary Nuker: Rage Cynthia.
Turn Sequence
- Strip and Boost: Your stripper moves first to remove enemy Will and shield buffs while advancing team attack bars.
- Buff and Break: Galleon casts Time to Loot to apply an AoE Defense Break and grant Cynthia an Attack buff.
- First Skill 2 Cast: Cynthia attacks before opposing damage dealers, firing her first Skill 2 to eliminate fragile units and heavily damage bruisers.
- Trigger Passive: Surviving enemy units counterattack and trigger Cynthia's survival mechanic instead of eliminating her.
- Follow-Up Casts: Cynthia executes her secondary and tertiary Skill 2 activations on subsequent turns or passive triggers to clean up remaining defenders.
Matchups and Limitations
This setup relies on glass-cannon stat distribution and specific turn flow. Avoid or plan around the following defensive checks:
- Nemesis Cutters: High-speed Nemesis healers (such as Ariel or Abellio) or Amduat can interrupt turn order between Galleon and Cynthia, cleansing the defense break or controlling your team before Cynthia moves.
- Oblivion: Passive-disabling effects from monsters like Tesarion or Isis prevent Cynthia's survival mechanic from triggering, cutting her rotation down to a single turn.
- Outspeed Strippers: Teams with superior Speed leads that strip Will runes can disable Cynthia before her initial cast, as her low defensive stats leave her vulnerable without immunity.
