Summoners War: Best Safe Guild Siege Offense Teams and Counters

To win Guild Siege battles reliably in Summoners War, build standardized, high-safety offenses rather than improvising counters. The primary danger on offense is uncontrolled enemy Violent rune procs. You can neutralize this variance by either deleting a critical threat before it takes a turn or using elemental baiting with heavy sustain so enemy streaks cannot wipe your units.

Before attacking, identify the enemy's primary damage dealer and defense breaker, then deploy one of three proven offense engines.

Defense-Ignoring Snipers: Copper and Bulldozer

Single-target defense-ignoring attackers bypass damage-reduction passives and shields, securing an immediate 3v2 advantage on turn one.

Copper (Wind Living Armor): His third skill, Thunder Strike, ignores defense only if his total Defense is higher than the target's (specifically, roughly double the enemy's Defense to guarantee the check). Pair him with Imesety, who provides both a Defense buff and Critical Rate buff alongside a 100% Attack Bar fill.
Bulldozer (Fire Frankenstein): His third skill, Full Swing, ignores defense unconditionally. Because the skill stuns Bulldozer after use, pair him with an immediate cleanser or turn cycler such as Racuni or Olivia.

Team Composition	Turn Order & Execution	Primary Target
Imesety, Copper, Bulldozer	Imesety boosts Copper → Copper deletes main threat → Bulldozer bursts second target	High-HP tank or primary defense breaker
Olivia, Bulldozer, Racuni	Olivia buffs DEF/ATB → Bulldozer bursts → Racuni cleanses stun to cycle	Fastest burst threat or enemy reviver
Khmun, Imesety, Copper	Imesety buffs Copper → Copper snipes core unit → Khmun shields survivors	High-threat bruisers after initial kill

Sniper Stat Benchmarks

Copper: Aim for at least +1,600 Defense and 160% Critical Damage on Guard and Will runes to consistently achieve 55,000+ damage under a Defense buff.
Bulldozer: Target +1,400 Defense, 160% Critical Damage, and at least 30,000 total HP so he survives incidental hits before firing.

Turn-Two Bruiser Engine: Feng Yan and Leo

When facing defenses packed with high-speed openers or multi-hit attackers, use a turn-two bruiser setup to absorb the initial assault and win through attrition.

Leo (Wind Dragon Knight): Leo's passive caps the combat speed of all monsters to his own speed, eliminating the enemy's Swift rune advantage and removing the need for high-speed runes on your teammates.
Feng Yan (Wind Panda Warrior): Feng Yan retaliates, applies Defense Break on his first skill, boosts his damage based on Defense, and gains Attack Bar whenever he takes damage.
Support Healer/Immunity: Pair Feng Yan with Woosa, Amelia, or Lulu and Friends to maintain immunity and cleanse incoming Defense Breaks.

Rules for Running Feng Yan Bruiser Teams

Bait enemy elements: Do not bring Feng Yan against heavy Fire burst threats (such as Perna or Douglas) without a durable Water tank to redirect attacks.
Stack Resistance: Keep Feng Yan's Resistance as close to 100% as possible. A Defense Break severely reduces both his survivability and his damage output.
Equip Destroy runes: Run Guard, Will, and Destroy sets so prolonged fights permanently reduce the max HP of stall defenses.

Deterministic Attrition: Bolverk and Mo Long

Against hyper-tanky defenses relying on deep HP pools, shields, and constant buffs, flat percentage-based damage eliminates targets without relying on conventional Attack or Defense stats.

Bolverk (Water Lightning Emperor): Gains stacks whenever any monster on the field receives a buff. At five stacks, his third skill drains 50% of the target's maximum HP and heals your team, bypassing defense and damage mitigation.
Mo Long (Water Panda Warrior): His third skill, Dragon's Dance, sacrifices 70% of his own current HP to deal 70% of the enemy's maximum HP as direct damage.

Execution

Field Bolverk and Mo Long alongside a multi-buff support such as Riley, Woosa, or Amelia.
Allow your support to grant multiple buffs, charging Bolverk to five stacks.
Use Bolverk’s skill three to reduce the primary enemy target by 50% max HP.
Follow immediately with Mo Long's Dragon's Dance to finish the target off, removing any risk of revives or defensive passives triggering.

General Rules for Targeting and Rune Safety

To maximize win consistency across all Siege attacks:

Equip Will Runes: Run Will sets across all monsters in turn-two and sniper offenses to prevent first-turn stuns, skill resets, and defense debuffs.
Eliminate the Defense Breaker First: Enemy defenses rely on Defense Break to trigger lethal burst. Removing the defense breaker eliminates the opponent's main win condition.
Respect Elemental AI: The game's defensive AI focuses on elemental advantage unless a unit is severely low on HP or defense-broken. Exploit this by bringing a tank weak to the enemy's main attacker, leaving your damage dealer untouched.
