To solo defend Wave 2 on Nightmare Frozen Field in ISEKAI GATE, anchor Mel directly at the mouth of the central ravine choke while dispatching your remaining units to sweep the outer map. Mel’s wide sweeping attacks and inherent bulk allow her to absorb Nightmare-scaled mob pressure without dedicated support, freeing secondary heroes to gather critical early-game economy.

Chokepoint Positioning and Wave Control

Place Mel slightly ahead of the central gate's collision box where the ravine narrows into the base. This positioning forces enemy spawns to compress into a tight column before they can fan out.

  • Funnel Placement: Keep Mel positioned at the opening of the ravine. Do not push deep into enemy territory, which exposes her to unreturned ranged fire.
  • Facing Angle: Anchor Mel facing outward toward the incoming spawn route. Turning back toward the gate disrupts auto-attack targeting and allows fast flankers to slip past.
  • Managing Ranged Attackers: When ranged mobs stop along the ravine rim outside Mel's melee reach, briefly tap her movement forward to catch them within her strike radius, then immediately return to the choke.

Skill and Stat Priorities for Wave 2

Nightmare difficulty increases enemy health, movement speed, and incoming damage. Mel needs area coverage and sustained survivability rather than single-target burst to hold the choke unattended.

  1. Area-of-Effect Damage: Upgrade skills that provide wide cleave, knockback, or ground impact. Broad attack arcs ensure basic attacks stagger entire clusters simultaneously.
  2. Sustain Modifiers: Prioritize early life-leech passives or health regeneration. These upgrades offset chip damage from stray ranged attackers and eliminate the need for healing items or roaming support.
  3. Flat Health and Defense: Add baseline defensive ratings once primary cleave skills are active to buffer against sudden wave spikes.

Full Map Clear Routing

Because Mel holds the central lane alone, secondary units can systematically sweep peripheral objectives during Wave 2. Clearing these camps early prevents resource decay and secures gear before harder waves begin.

Priority 1Northern Icy CachesYields early gold to fund offensive skill upgrades.
Priority 2Breakable BarricadesClears pathways for rapid hero repositioning across lanes.

Send your most mobile hero to clear the northern caches and ice crystals first. Once the northern route is cleared, rotate down to defeat the southern elite mini-bosses.

Transitioning to Wave 3

As the final Wave 2 enemies fall, immediately recall all roaming heroes to the central gate perimeter. Nightmare Frozen Field escalates significantly on Wave 3, introducing higher-speed mobs and armored vanguards that require consolidated team fire to defeat.
