To beat Mentor Leilei in Level 75 Challenge Mode while underleveled in Aniimo, you must field a utility-heavy team that relies on active mitigation, crowd control (CC) interruptions, and strict target prioritization. At a steep level deficit, trading damage directly results in instant squad wipes. Securing the "Imprisoning Bind" badge requires absorbing the opening assault, eliminating high-damage secondary adds, and repeatedly canceling Leilei's energy rotations.
Stage Modifiers and Threat Rules
Because Leilei's team scales to Level 75, an underleveled squad faces harsh damage-scaling penalties and specific encounter restrictions:
- Lethal Incoming Damage: Direct, unmitigated hits from frontline enemies can cut squishy units down in a single blow, while full ultimate casts cause total squad wipes.
- Accelerated Enemy Energy: Opponents build ability meters faster than normal, requiring manual interruptions rather than passive cooldown trading.
- Crowd Control Resistance: Enemy units feature elevated baseline CC resistance, meaning generic or delayed disables will often fail to interrupt dangerous skills in time.
- Displacement Hazards: Leilei's formation uses positioning skills that pull fragile backline units into the frontline danger zone.
Recommended Team Roster and Roles
Raw damage statistics cannot outpace Level 75 defensive pools when you are underleveled. Shift your team composition toward damage absorption, cleanse utility, and targeted lockdown.
| Team Slot | Primary Role | Core Objective | Key Stat Priorities |
|---|---|---|---|
| Frontline Anchor | Tank / Mitigation | Absorb opening burst and hold enemy aggression | Max HP, Physical/Elemental Defense, Cooldown Reduction |
| Primary Controller | Hard Crowd Control | Interrupt casting bars with stuns, binds, and roots | Speed, Effect Hit Rate, Energy Recharge |
| Tactical DPS | Single-Target Burst | Eliminate disabled priority targets rapidly | Critical Rate, Attack, Armor Penetration |
| Defensive Support | Shielding / Cleansing | Remove binds and buffer incoming burst damage | Energy Recharge, Shield Strength, Healing Output |
Essential Skill Selections
Select active skill loadouts that counter stage mechanics rather than broad area-of-effect abilities:
- Controller Skills: Equip low-cooldown, single-target hard disables such as direct stuns or immobilizing roots. Avoid multi-hit skills with long cast animations that fail to stop incoming casts immediately.
- Support Skills: Bring rapid cleanses to remove immobilizing and binding debuffs applied to your main attacker, paired with reactive shielding to cushion unavoidable area damage.
- DPS Skills: Choose instant-activation burst abilities or skills with invulnerability frames during execution. Avoid channeled skills, as enemy crowd control or high incoming damage will interrupt them.
Step-by-Step Combat Execution
Winning the trial requires managing threats in sequence rather than attacking Leilei immediately.
1. Absorb the Opening and Eliminate the Primary Add
- Cast your tank's defensive mitigation skill immediately upon loading into the arena to survive the initial burst.
- Do not spend damage cooldowns on Leilei at the start.
- Locate the lowest-defense, high-damage enemy add and apply your controller's primary stun immediately.
- Focus all single-target burst onto that stunned target to remove them from the field, eliminating a massive portion of the enemy team's total damage output.
2. Control Leilei's Energy and Clear Secondary Supports
- Watch Leilei's animation for her telegraphed skill windup.
- Save your controller's secondary interruption and trigger it the moment her casting bar appears to cancel the skill and reset her energy cycle.
- Refresh defensive shields and cleanse any lingering roots or slows while Leilei is incapacitated.
- Direct your damage rotations into the remaining secondary support units until Leilei is completely isolated.
3. Handle Isolated Leilei and Claim the Badge
Once alone, Leilei enters an aggressive pattern featuring faster cooldowns, wide area attacks, and damage-reflecting guards:
- Angle your tank toward the perimeter of the arena to keep directed strikes aimed away from your squishier units.
- Bait out her ground-targeted area attacks by moving your active unit along the outer edge of the combat space.
- Never deploy major burst cooldowns while her active guard is raised; wait until your controller applies a fresh stun or knockdown before attacking.
- Chip her remaining health pool down methodically through successive stun windows.
Depleting her health bar completes the challenge and awards the "Imprisoning Bind" badge.

I wish I had read this before upgrading the wrong thing.
This helped me understand strategy much better.
This saved me time in the early game.
Good guide for Aniimo players. The strategy part was useful.
