Summoners War Manannan Build Guide: Runes, Stats, and Teams

To maximize Dark Sea Emperor (Manannan) in Summoners War after his balance patch damage increase, build him as a dedicated single-target burst nuker equipped with either a turn-one Rage/Will set or a cycling Violent/Will set. Manannan relies on his passive ability, Impartial Arbiter, to finish high-priority targets under defense-break conditions. He requires strict speed-tuning behind an attack buffer and armor breaker, backed by high Attack, 100% Critical Rate, and heavy Critical Damage.

Rune Set Comparison: Rage vs. Violent

Your choice of primary four-set rune configuration depends on whether you run a turn-one cleave offense or an extended combat team.

Rage / Will (Turn-One Nuker)

Rage provides an extra 40% Critical Damage, which stacks multiplicatively with Manannan's passive damage scaling to secure one-shot kills on tanky bruisers like Beast Monks, Archangels, and defense scalers. Use Will as the offset to protect him from pushbacks, provokes, or cut-ins. If your substats fall short of the required Critical Rate cap, use a Blade set until your rune quality improves.

Violent / Will (Sustained Threat)

Violent is the preferred setup when facing revive mechanics (such as Nana or Vanessa) or extended World Arena matches. Extra turn procs allow Manannan to follow up an initial strike with his second skill or re-engage after defense breaks are reapplied. This build requires investing in survivability substats (HP% and Def%) so he does not collapse under focused enemy damage.

Core Stat Benchmarks

Manannan provides no defensive team utility, so every stat must support turn order, hit reliability, and raw burst. Target the following benchmarks on Slot 2, 4, and 6 (typically Spd or Atk% / Crit Dmg% / Atk%):

• Critical Rate (85% to 100%): Aim for 100% Critical Rate to eliminate damage variance against neutral elements. An 85% Critical Rate is only sufficient when striking Light targets with elemental advantage.
• Critical Damage (160% to 210%+): Aim for 200%+ on Rage sets. On Violent builds, aim for 160% to 180% to leave room for survival substats.
• Attack Power (+1,500 to +2,000): Stack raw flat attack and percentage attack to scale his base attack value before passive multipliers take effect.
• Speed (+90 to +130): Tune his Speed to move immediately after your team's defense breaker and attack buffer to prevent enemy Nemesis cut-ins or cleansers from interrupting.

Artifact Stat Priorities

Because Manannan's kit focuses on single-target damage scaling based on target health, select conditional Critical Damage lines on both his Attribute and Type artifacts over flat utility stats:

• Primary Substats: [Skill 1 Crit Dmg +%], [Skill 2 Crit Dmg +%], and Crit Dmg+ as Enemy's HP is High. Boosting damage against high-health targets ensures his opening attack drops tanks into finishing range.
• Secondary Substats: Damage Dealt on Light/Dark +%, Single-target Skill Crit Dmg +%, and Crit Dmg+ as Enemy's HP is Low.
• Low-Priority Options: Life Drain or Additional Damage by Atk offer minor utility but provide significantly lower burst value than direct Critical Damage percentage increases.

Team Compositions and Turn Order

Manannan lacks innate attack buffs and area-of-effect defense breaks, meaning he cannot function effectively without support setup.

Fast Siege and Arena Cleave

Pair Manannan with an Attack Bar booster and an AoE defense breaker to guarantee clean first-turn picks:

1. Attack Bar Buffer (Eshir or Bastet): Secures first turn and pushes team attack gauges.
2. Setup Enabler (Galleon, Gemini, or Clara): Strips enemy buffs, applies Defense Break, and supplies an Attack Buff.
3. Executioner (Manannan): Targets and removes the opponent's core threat before they take a turn.

World Arena (RTA) Control Hybrid

Drafting Manannan as a pure glass cannon leaves him vulnerable to heavy crowd control. In RTA drafts, pair him with fast control bruisers who bring single-target defense breaks:

• Run him alongside units like Sagar, Savannah, or Ethna.
• These units force opponents to ban immediate crowd-control threats, allowing Manannan to exploit defense breaks and punish slow, passive tank teams.
