Omniheroes Season 17 Lost City Guide: How to Clear All 800 Floors

To clear all 800 floors of the Lost City in Omniheroes Season 17, build your teams around percentage-based damage synergies rather than flat attack power, schedule defensive Relic triggers for the opening round, and adjust hero placement to control enemy target priority. Scaling enemy health pools and damage output quickly outpace raw Combat Power, making turn-one survivability and debuff mitigation essential to surviving the upper floors.

Core Team Roles and Recommended Synergies

Flat damage dealers lose effectiveness as enemy stats inflate across the tower. To prevent reaching the battle turn limit, prioritize Doomers and Mystifiers for their escalating percentage health burns, continuous damage-over-time effects, and defense shredding. Anchors such as Franz and Macaria help disrupt enemy opening skills while your primary damage dealers build the rage required for full ultimate rotations.

If you deploy physical burst synergies such as Valiants or Avengers, tune your speed order so support buffers apply attack and critical rate increases before your primary attacker takes action.

Countering Boss Floors Ending in 50 and 00

Milestone checkpoints on floors ending in 50 and 00 introduce boss mechanics centered on massive shields, rapid health regeneration, or temporary immunity windows. Pushing through these stages with unoptimized damage leads to turn-limit defeats.

• Strip damage shields: Ensure your dispeller or debuffer acts directly ahead of your main carry in the turn order. Stripping damage-reduction buffs right before your burst window prevents wasted ultimate rotations.
• Apply unremovable anti-heal: When bosses regenerate health faster than your damage accumulates, replace a secondary damage dealer with a support that applies continuous healing reduction.
• Manage immunity timing: Hold secondary burst skills until enemy damage-immunity windows expire rather than casting skills on cooldown.

Relic Setup and Trigger Timing

High-tier Lost City pushing requires separating defensive Relic procs from offensive damage spikes:

1. Equip defensive Relics for round one: Floor 500 and above feature high opening enemy burst. Frontload shields and damage reduction at the start of battle so squishy supports and control units survive to trigger their abilities.
2. Delay offensive Relics for carry ultimates: Avoid setting offensive Relics to fire on round one, where enemy shields or invulnerability states absorb the impact. Sync your damage Relics with your main carry’s ultimate rotation to crack enemy frontlines during vulnerable windows.

Handling Floor 600 to 800 Stage Penalties

The final 200 floors impose passive environmental hazards, including reduced healing efficacy, lower base rage generation, and enemy counter-attack triggers. Standard hyper-offensive glass cannon teams will wipe before executing their rotation.

• Mandatory cleanse utility: Carries afflicted with round-one stuns, silences, or stacking damage debuffs cause instant failure. Run cleansers that clear negative status effects at the start of the round to ensure your damage cycle functions.
• Splash damage protection: Reposition your primary carry away from allies targeted by enemy cleave attacks to avoid accidental collateral deaths.
• Transition to hybrid sustain: Blend hard control with burst windows rather than relying on pure damage, as enemy retaliations can one-shot unprotected carries through baseline defenses.

Repositioning and RNG Management

Wiping in the first few seconds of a fight usually indicates a targeting issue rather than insufficient stats. Lost City enemies follow predictable placement rules when selecting targets.

Use the battle replay feature to identify which enemy ability triggers your team's collapse. Move squishy supports away from the center backline to exterior corners to redirect focus fire, and position your primary tank directly opposite the enemy's main burst threat.

When a stage relies on landing an opening crowd-control check or critical hit, multiple automatic attempts may be necessary. If a lineup fails consistently, adjust rune speeds slightly so your crowd-control unit acts just ahead of the enemy carry before overhauling your entire roster.
