Summoners War Fire Worm Cleave Build and RTA Draft Guide

You can run Fire Worm (Volcaris) as a cleave damage dealer in Summoners War World Arena (RTA), but only if you replace standard pure-HP tank runes with an offensive Critical Damage build. Because Volcaris scales from maximum health rather than Attack, he can deliver heavy area-of-effect burst while retaining enough natural bulk to survive counterattacks, nemesis interrupts, and passive revenges that normally eliminate traditional glass-cannon nukers.

To make the strategy work, you must speed-tune Volcaris behind dedicated attack bar manipulation and area defense break, as he cannot penetrate high-defense targets on his own.

Rune Builds and Stat Benchmarks

A cleave setup requires Volcaris to move immediately after your setup debuffers and secure lethal damage against defense-broken enemies.

Rune Slot / Stat	Cleave Specification	Target Benchmark
Primary Set	Rage or Swift	Rage for peak burst; Swift if you lack speed substats
Secondary Set	Will or Blade	Blade to cap Critical Rate; Will to counter turn cuts
Slot 2 / 4 / 6	HP% / Crit Damage / HP%	Use Slot 2 Speed only if substats cannot reach the turn order
Critical Rate	85% to 100%	85% minimum for Wind targets; 100% for full reliability
Critical Damage	150% to 180%+	Multiplies his base HP scaling into lethal territory
Bonus Speed	+100 to +130	Tuned directly behind your defense breaker
Bonus HP	+25,000 to +35,000	Provides both his damage scaling and survivability

Artifact Priorities

Equip artifacts that offer maximum flat HP on both the left and right sides to expand his damage pool. Focus on substats that increase Critical Damage on his primary damage skill and damage based on added or remaining HP. For defense, prioritize damage reduction from common elemental threats to survive counter-cleaves.

Turn Order and Team Setup

Volcaris does not bring inherent defense break on his primary burst skill. To secure clean wipes, your team must execute a strict four-step turn order:

First Turn Stripper and Booster: Use fast initiators like Chiwu, Moore, or Eshir to take turn one, strip enemy Will runes, and control opposing attack bars.
Area Defense Break: Follow immediately with an area defense breaker such as Savannah, Luer, or Galleon to reduce enemy armor and apply secondary debuffs like slow.
Volcaris Cleave: Fire Worm takes his turn, using his HP-scaling attack to crush the defense-broken enemy team.
Single-Target Finisher: Bring a secondary damage threat such as Sonia or Dominic to eliminate any high-priority units that survive the initial blast.

When to Draft Cleave Volcaris

Draft Volcaris into speed-contest teams, squishy control compositions, and turn-two setups that lack heavy Water sustain. Opponents often mistake Volcaris for an unthreatening tank in draft lobbies, frequently wasting their bans on visible control units and letting him slip through unpunished.

Draft Limitations and Counters

Pivot away from a Volcaris cleave under the following conditions:

Heavy Water Sustain Cores: Units such as Riley, Woosa, and Chow impose elemental glancing checks, large shields, and continuous healing that absorb his burst.
Failed Defense Breaks: If your defense breaker is banned during draft or resisted during the opening turn, Volcaris lacks the raw multiplier to kill bulky units through raw defense.
