ISEKAI GATE: Campaign Squad Setup and Progression Guide

To clear campaign stages consistently in ISEKAI GATE, concentrate your upgrade materials into a primary damage dealer and a frontline tank while arranging your squad on the grid to protect fragile backline units. Spreading enhancement materials evenly across a full roster dilutes your combat power and causes progression to stall early.

Grid Positioning and Line of Sight

Enemy waves in ISEKAI GATE acquire targets based on direct line of sight before switching to adjacent lanes. Placing fragile damage dealers or healers in forward tiles exposes them to immediate focus fire before their skill gauges charge.

Organize your party across the grid using three primary depth tiers:

Frontline Tanks: Place high-health defenders and shielding units in the front row, directly opposing the largest enemy cluster to absorb initial normal attacks.
Midline Bruisers and Utility: Position hybrid fighters and buff-oriented supports directly behind the front row to intercept stray melee enemies without taking primary boss aggro.
Backline Carries and Healers: Keep ranged damage dealers and sustain healers in the rear tiles so they can generate skill energy uninterrupted.

When facing boss encounters with piercing line attacks or rear-cleave abilities, stagger your units into separate rows rather than lining them up directly behind one another. This reduces collective area-of-effect damage and protects your backline support units from multi-target hits.

Resource Allocation and Hero Leveling Priorities

Progression in ISEKAI GATE centers on unlocking milestone promotions that grant passive skill nodes and major percentage stat multipliers. To maintain steady stage clears, funnel your gold, experience, and ascension materials into your primary carry until they hit their current level cap before distributing leftover resources to defensive anchors.

Priority	Role Target	Upgrade Focus	Purpose
Top Priority	Primary Area-of-Effect DPS	Level caps, skill upgrades, main weapon	Clears standard mob waves quickly to stop party attrition.
High Priority	Main Frontline Defender	Level caps, defensive armor, HP nodes	Holds enemy focus and survives burst mechanics.
Medium Priority	Sustained Healer	Skill levels, energy regeneration, survival gear	Stabilizes the frontline through extended encounters.
Lower Priority	Secondary Utility / Buffers	Base survival thresholds, passive utility	Provides stat boosts without requiring heavy material investment.

Gear Upgrades and Stat Matching

Equip gear that aligns directly with your hero's damage scaling profile, matching physical attack or magical power accordingly.

Do not spend high-tier upgrade stones on early white or green gear that will be replaced quickly. Enhance low-tier equipment only to the minimum threshold required to survive current story checks. Once rare and epic equipment begins dropping from campaign completion chests and advanced nodes, invest your materials into pieces featuring percentage attack, critical strike chance, and flat defense.

Combat Control and Boss Tactics

Auto-battle activates abilities as soon as they charge, which frequently expends high-value crowd control and area-burst skills on weakened mobs right before a boss spawns. Take manual control when pushing new story chapters and difficult boss stages:

Pool Energy Before Boss Waves: Rely on basic attacks to defeat the last few enemies of preliminary waves so your team enters the final wave with fully charged skill gauges.
Interrupt Wind-Up Animations: Save stuns, silences, and knockbacks for when the boss displays a glowing telegraph or charge animation. Interrupting these skills prevents severe party-wide damage.
Chain Buffs Before Burst Attacks: Cast team attack power amplifiers and enemy defense debuffs immediately before triggering your primary carry's ultimate skill to maximize output during damage windows.
Counter Enrage Timers: If an encounter hits an enrage timer or stage timeout, your damage output is too low. Replace a redundant secondary healer or defensive buffer with an additional burst attacker to increase total squad damage.

Energy Management and Stage Sweeps

Avoid letting your stamina pool sit at its maximum cap, as capped stamina stops natural energy recovery. Push your campaign progress as far as your current battle power allows before spending remaining energy.

Once you achieve a three-star clear on a stage, use the sweep function to farm promotion badges, gear enhancement materials, and account experience instantly. Target your daily sweeps exclusively toward the specific rank-up materials required for your primary carry's next promotion milestone.
