Summoners War: Fire ROBO (ROBO-E65) RTA Build and Draft Guide

To counter turn-cycling teams in Summoners War World Arena, build Fire ROBO (ROBO-E65) with high Speed and Accuracy on either Despair or Swift runes, and draft it late as a reactive counterpick. Its passive grants massive Attack Bar whenever an opponent takes an additional turn, enabling ROBO-E65 to cut into enemy attack chains, strip beneficial effects, and absorb Attack Bar across the entire enemy team.

How the Turn-Cutting Passive Works

ROBO-E65 disrupts compositions that rely on consecutive turns, whether generated by Violent rune activations or skill-based extra turns.

Trigger Conditions: Whenever an opposing unit gains an extra turn—such as Oliver cycling skill resets, Diana changing forms, or any unit triggering a Violent proc—Fire ROBO gains a large chunk of Attack Bar.
Intercept Window: The passive does not stop the initial attack, but it frequently fills ROBO-E65's Attack Bar to 100% before the opponent can use their bonus turn.
Immediate Retaliation: Once Fire ROBO cuts in, deploying Skill 2 (Electromagnetic Discharge) strips enemy Immunity and shields while absorbing enemy Attack Bar to reset their offensive momentum.

Rune Builds and Stat Benchmarks

Rune selection depends on whether your team requires additional crowd control or raw speed to contest high-tempo initiators.

Build Archetype	Primary Set	Secondary Set	Slot 2 / 4 / 6	Priority Substats	Target Benchmarks
Control Disruptor	Despair	Will	SPD / HP% / ACC% or HP%	SPD, ACC, HP%, DEF%	65%+ Accuracy, high effective HP
Speed Interceptor	Swift	Will	SPD / HP% / HP%	SPD, ACC, HP%, DEF%	+160 to +180 bonus Speed
Bruiser Hybrid	Despair	Revenge	SPD / HP% / DEF%	SPD, HP%, DEF%, ACC	Balanced survival and chip utility

Despair Build

Despair is standard for balanced and turn-two compositions. Because Skill 2 attacks all enemies to strip buffs and absorb Attack Bar, Despair grants a secondary roll to stun each target. If an enemy resists the Attack Bar reduction, the Despair stun can still halt their turn entirely. Aim for at least 65% Accuracy to land buff strips consistently.

Swift Build

Swift suits high-tempo drafts contesting turn-one threats. It sacrifices the chance for bonus stuns in exchange for guaranteed turn-stealing velocity. A swift set with +160 to +180 bonus Speed ensures that even a single extra turn from an enemy booster pushes ROBO-E65 over the cutoff threshold before secondary single-target nukers can follow up.

Draft Strategy and Synergies

Draft Fire ROBO strictly as a reactive 4th or 5th pick in World Arena to punish specific team structures.

Target Matchups: Pick ROBO-E65 into units with built-in extra turns, such as Diana, Oliver, Miles, Helena, and Seara. Multi-turn rotations from these units rapidly trigger ROBO-E65's passive, guaranteeing an immediate cut.
Draft Positioning: Never pick Fire ROBO within the first three slots. Committing early lets the opponent pivot away from bonus turns into direct, single-action cleaves or hard control units that bypass the passive.
Allied Synergies: Pair ROBO-E65 with durable bruisers and controllers like Karnal, Shizuka, or Riley. Once Fire ROBO strips Will runes and absorbs attack bars, follow-up units can safely apply crowd control or secure defensive buffs.

Matchup Weaknesses

Do not draft Fire ROBO into the following archetypes:

Single-Turn Cleaves: Fast cleave teams using units like Sonia, Kahli, or standard Lushen boosters do not rely on Violent procs or extra turns to eliminate targets. Fire ROBO will remain idle without passive triggers.
Oblivion Debuffs: Passive-disabling skills from monsters like Tesarion or Herne completely shut down ROBO-E65's Attack Bar generation, reducing it to low-threat utility.
Water Control Threats: Water units hold elemental advantage. Units like Moore and Shizuka can absorb hits, resist strips, or reverse debuffs back onto your team.
