Guild of Monster Girls: EX4 Free and Welfare Unit Clear Guide

To clear Stage EX4 in the Vice Guildmaster event with event-reward and free welfare units, place a durable melee blocker directly into the path of the Triple Cannon and coordinate your burst skills during the brief window when all seven deployment slots are filled. Engaging the artillery piece in close quarters prevents it from wiping your backline ranged units with explosive area-of-effect damage.

Neutralizing the Triple Cannon

The Triple Cannon serves as the primary lethal threat on Stage EX4. Left unimpeded, its long-range barrage can eliminate fragile ranged damage dealers and healers within two attack cycles.

To shut down this threat, intercept the artillery piece as it reaches your frontline choke point:

Intercept at the forward tile: Deploy a high-durability melee unit directly onto the path the cannon travels—specifically the position typically held by frontline blockers like Med.
Force close-quarters aggro: Engaging the Triple Cannon in melee locks it into single-target attacks against your designated tank, neutralizing its ranged area damage.
Anchor with dedicated healing: Keep a ranged healer positioned outside the cannon's line of fire to sustain the blocker through continuous physical and explosive hits.
Deploy ahead of range: Place the blocker slightly before the cannon enters firing range. Late placement allows the cannon to launch an initial salvo that can destroy your backline.

Managing the Seven-Unit Deployment Window

Stage EX4 provides limited deployment resources, and the window where you have all seven units active at the same time is very short. Filling every slot early leaves no room to rotate units or respond to elite spawns.

Build your board gradually across four distinct phases:

Phase	Active Units	Tactical Priority
Opening	2–3 Units	Deploy cost generators and light vanguards to eliminate early runner waves.
Mid-Wave	4–5 Units	Set up primary ranged DPS and healer coverage overlooking the central lane.
Elite Clash	7 Units	Deploy the Triple Cannon blocker and trigger all active burst skills together.
Cleanup	3–5 Units	Retreat damaged blockers and cycle slots to clean up remaining stragglers.

Because all seven units remain on the field together for only a short period, activate offensive buffs and damage cooldowns simultaneously when the Triple Cannon and its escort reach the kill zone.

Welfare Team Roles and Execution Checks

A successful budget composition requires role compression to meet the stage's stat checks without rare gacha units:

Primary Melee Blocker: A sturdy frontline defender capable of withstanding direct boss hits at the intercept point.
Secondary Off-Tank: A reserve melee unit ready to immediately drop onto the tile if the primary blocker takes fatal damage and must be retreated.
Overlapping DPS: Ranged and area-of-effect damage dealers oriented so their attack ranges overlap directly on the blocker's tile, clearing escort minions passively.
Sustained Healer: A support unit dedicated to keeping the frontline tank alive throughout the duel with the cannon.

Save your healer's emergency recovery skills for the Triple Cannon engagement rather than spending them on early fodder waves. Maintaining unbroken melee contact on the cannon until it falls ensures a stable clear.
