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.

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.

  • 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

  1. Strip and Boost: Your stripper moves first to remove enemy Will and shield buffs while advancing team attack bars.
  2. Buff and Break: Galleon casts Time to Loot to apply an AoE Defense Break and grant Cynthia an Attack buff.
  3. First Skill 2 Cast: Cynthia attacks before opposing damage dealers, firing her first Skill 2 to eliminate fragile units and heavily damage bruisers.
  4. Trigger Passive: Surviving enemy units counterattack and trigger Cynthia's survival mechanic instead of eliminating her.
  5. 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.
