What Makes EX-08 Different
EX-08 introduces a multi-layered teleporter network requiring specific activation sequences. Standard stages follow linear paths where combat power determines success. EX-08 demands both combat strength and puzzle-solving skills.
The teleport puzzle creates branching paths where wrong choices send you backward or into dead-end loops. However, checkpoints preserve progress milestones, preventing complete restarts in most situations.
Minimum Combat Power and Prerequisites
Reach Campaign Chapter 15+ before attempting EX-08. Recommended combat power: 180,000+ for sufficient damage and survivability.
Team composition matters more than raw power. A balanced squad with DPS, healing, and burst damage outperforms higher-power teams lacking synergy. The Bastion Cube from Lost Sector 07 provides ammo refunds for sustained damage dealers, while the Assault Cube from Lost Sector 01 increases hit rate.
Stamina Cost and Rewards
Each attempt consumes standard Lost Sector stamina, making failed runs costly. The Bastion Battery is the primary reward, contributing to battery collection for Union Chip exchanges.
Solo Raid allows farming up to 6 batteries daily, but Lost Sector stages provide targeted battery types unavailable elsewhere. Exchange rate: 10 batteries = 2000 Union Chips.
Why the Puzzle Frustrates Players
The teleport puzzle lacks in-game visual indicators showing correct sequences, forcing trial-and-error or external guides. Teleporter activation appears identical regardless of correctness.
Many assume any wrong choice triggers complete resets, leading to premature abandonment. This wastes stamina. The checkpoint system actually preserves progress at specific milestones, allowing recovery from most errors without full restarts.
Teleport Puzzle Mechanics Explained
How Teleporters Function
Teleporters operate as directional transport nodes moving you between distinct areas. Each connects to predetermined destinations based on activation order, not physical proximity. This non-linear design creates the puzzle element.
Activating a teleporter immediately transports your squad, triggering associated combat or puzzle elements. No preview of destinations makes blind attempts risky.
Understanding Checkpoints
Checkpoints activate automatically at specific milestones, creating save points that persist after retreating or failing combat. These preserve teleporter progress, letting you resume from the last checkpoint.
Checkpoints trigger after completing certain combat waves and reaching designated teleporter nodes. This enables multi-session attempts for undergeared teams.
What Triggers Full Resets
Full resets occur only when you manually select stage reset or complete it successfully. Wrong teleporter choices don't trigger automatic resets.
Combat failures return you to the most recent checkpoint, not the stage beginning. This forgiving system allows undergeared teams to progress incrementally across multiple attempts.
Visual Map of Teleporter Locations
EX-08 contains multiple teleporter nodes across three zones: entry corridor, central puzzle chamber, and boss approach pathway. The entry corridor has two teleporters branching into separate routes. The central chamber contains four interconnected teleporters forming the core puzzle.
The boss approach pathway includes final teleporters converging on the boss arena entrance.
Complete EX-08 Teleport Puzzle Solution
Starting Position and First Teleporter
Begin at the stage entrance facing two teleporters. Choose the left teleporter, transporting you to the central puzzle chamber's western entrance.
The right teleporter sends you to a combat-heavy detour that loops back, wasting time. The left path minimizes combat before the core puzzle.
Correct Sequence for Teleporters 2-4
Upon entering the central chamber, activate the northern teleporter among four visible options. This triggers the first checkpoint.
The third teleporter is the eastern node in the next chamber. This advances toward the boss pathway while avoiding loops. A second checkpoint activates after clearing the combat wave.
The fourth teleporter appears as a single option in the corridor. This forced choice advances automatically, triggering a moderate combat encounter.
Mid-Stage Combat Encounters
Combat features mixed enemy compositions including shielded units and ranged attackers. Prioritize shield-breaking with appropriate weapon types. Use burst skills to eliminate clustered enemies quickly.
The Onslaught Cube from Lost Sector 02 increases charge damage by 3.81%. The Resilience Cube from Lost Sector 04 improves reload speed for sustained damage.
Final Teleporter Sequence to Boss
The final section presents three teleporters in triangular formation. Correct sequence: center, then right, then the single teleporter that appears. This unlocks the boss arena entrance and triggers the final checkpoint.
Wrong choices loop you back to the previous checkpoint, not the stage beginning, allowing quick correction.
What to Do If You Take a Wrong Teleporter
Wrong choices typically transport you to previous areas or combat loops, not progress resets. Identify your location by observing enemy compositions and teleporter arrangements, then reference the correct sequence.
If looped back to a checkpoint area, resume the correct sequence from that point. For severe errors, retreat to menu and resume from last checkpoint without full stage reset.
Optimal Team Composition
Best DPS NIKKEs
High-burst damage dealers excel in wave-based combat, eliminating enemies before they overwhelm you. Units with area-of-effect capabilities clear clustered enemies efficiently.

Common Mistakes That Reset Progress
Misconception #1: All Teleporter Mistakes Reset Everything
The most prevalent misconception assumes any wrong choice triggers complete progress loss. The checkpoint system prevents this, preserving progress at designated milestones.
Players who abandon runs after single wrong choices waste stamina unnecessarily. Understanding checkpoints enables persistent progression through trial-and-error.
Misconception #2: Must Complete in One Attempt
Multi-session attempts remain viable through checkpoint preservation. You can retreat after reaching checkpoints, returning later without losing puzzle progress.
This flexibility benefits players balancing multiple daily activities, allowing EX-08 progression across several sessions.
How to Safely Retreat
Access the pause menu during non-combat moments and select retreat. This preserves checkpoint progress while returning stamina proportional to remaining completion. Retreating during combat may forfeit that encounter's progress but maintains checkpoint status.
Verify checkpoint activation by noting the notification after specific teleporter sequences and combat completions.
When to Reset vs Push Forward
Intentional resets make sense when early errors create inefficient paths requiring excessive backtracking. Evaluate whether correcting the current path costs more time than restarting with correct sequence knowledge.
For players near completion with minor errors, pushing forward typically proves more efficient.
Advanced Tips for Efficient Farming
Speed-Running Strategies
Memorize the exact teleporter sequence and optimal combat strategies to minimize clear times. Experienced players complete EX-08 significantly faster by eliminating exploration time and optimizing damage rotations.
The Bastion Cube's ammo refund mechanic supports sustained damage during speed runs, reducing reload downtime.
Stamina Efficiency
Evaluate EX-08 repetition against alternative stamina uses based on progression priorities. The Bastion Battery's value depends on battery collection goals and Union Chip needs.

Exchange rate: 10 batteries = 2000 Union Chips establishes baseline value calculations.
Tracking Progress Across Sessions
Maintain external notes documenting checkpoint progress and teleporter sequences during multi-session attempts. This prevents confusion when resuming interrupted runs.
Screenshot checkpoint notifications or teleporter configurations for visual references.
Troubleshooting Guide
Teleporters Seem Broken
Apparent malfunctions typically result from misunderstanding sequence requirements. Verify you're activating teleporters in the documented correct order, as similar-looking teleporters in different zones create confusion.
Restart the game client if teleporters genuinely fail to activate, as rare technical issues can prevent proper functionality.
Recovering From Wrong Choices
Identify your current location and reference the correct sequence to determine the next step. Most wrong choices create loops back to previous checkpoints, not dead ends.
Systematic exploration of available teleporters eventually reveals the correct path forward.
Combat Power Too Low
Players lacking sufficient power should focus on equipment enhancement, NIKKE leveling, and skill upgrades before repeated attempts. The stage assumes specific power thresholds undergeared teams can't overcome through skill alone.
Alternative Lost Sector stages provide progression opportunities while building power. The Assault Battery from Lost Sector 03, Onslaught Battery from Lost Sector 05, and Resilience Battery from Lost Sector 06 contribute to battery collection without EX-08's difficulty.
Technical Issues
Persistent problems require game client restarts or cache clearing. Verify stable internet connectivity, as connection interruptions during teleporter activations can create desynchronization.
Contact official support if problems persist, providing specific details about teleporter behavior.
Resource Optimization
Gems for Stamina Refreshes
