The Mechanics of Infinity

Essential Reading

Why Normal DPS Fails

Infinite Mode isn't just "harder" - it fundamentally changes the math. By Wave 100, enemies have HP in the Quintillions.

A unit dealing 1 Trillion damage per second hits like a wet noodle (0.00001% HP). To survive, you MUST use one of these mechanics:

  • Infinite Scaling DOT — Damage that stacks continuously without a cap (Kyito with Astral trait)
  • Time Rewind — Physically moving enemies backward to buy time (Lelouch's Zero skill)
  • Percent HP Damage — Damage calculated as a percentage of max health

Meta Unit Spotlights

Top Picks
SSS TIER

Ichigo Winter

Nuke / Boss Killer

The new king of burst damage. While Kyito handles the scaling mobs, Ichigo is mandatory for instantly deleting the massive HP bosses that appear every 10 waves.

Trait: Reaper (Crit) Relic: Demonic Essence Target: Strongest
SSS TIER

Ice Empress Winter

Hybrid CC / Summoner

A game-changer for stalling. She combines Dragon Guy's freeze with summons that block enemies. Essential for buying time for your DOTs to tick.

Trait: Ethereal (-CD) Relic: Frozen Heart Role: Perma-Freeze
SSS TIER

Kyito — The God of Infinite

Main Carry / Infinite Scaling

The single most important unit for this mode. Without him, Wave 80 is your hard cap. His bleed stacks infinitely when paired with Astral trait.

Trait: Astral (Required) Relic: Master Ninja Synergy: Miku, Dragon
Pro Tip: Astral increases DOT duration, allowing bleed stacks to overlap.
SSS TIER

Lelouch — The Time Lord

Stall / Last Resort

The panic button. When enemies are about to leak, use his active ability to rewind them back to the start. Essential for resetting enemy positions.

Trait: Lightspeed (-CD) Relic: Laughing Captain Active: "Zero" (Rewind)
SSS TIER

Fastcart

Hyper Economy

You cannot survive without maxed upgrades. Fastcart provides 3x the money of Speedwagon, allowing you to max your board by Wave 30.

Trait: Greed ($$$) Placement: Start of Map Priority: Max First

The Road to Wave 100

Step-by-Step
1
Economy Rush Wave 1-20

Do not build defense unless you are about to die. Build money.

  • Place Speedwagon instantly.
  • Use a cheap "Wave Clearer" (Ragna/Jinoo) at the front.
  • Pour every dollar into Speedwagon. Goal: Max Speedwagon by Wave 15.
2
The Kill Zone Wave 20-50

Construct your "Death Ball" in a corner.

  • Place Miku to cover the corner. Max her range buff.
  • Place Kyito inside Miku's buff. Set to "Strongest".
  • Place Dragon Guy at the entrance of your kill zone.
3
The Stall Cycle Wave 80+

Manual Mode engaged. You cannot AFK anymore.

  • Step 1: Wait for enemies to reach Dragon Guy's freeze.
  • Step 2: Let Kyito attack freely to stack bleed.
  • Step 3: When freeze ends, cast Lelouch's Rewind.
  • Step 4: Repeat. This cycle allows Kyito to stack damage to infinity.

Frequently Asked Questions

Does Ruler Trait work on Kyito?
NO. Ruler gives raw damage. Kyito kills with DOT. Raw damage is useless past Wave 80. You specifically need Astral to extend the DOT duration.
Can I use Ace instead of Kyito?
Yes, but Ace's burn stacks slower and has a lower cap. Kyito is SSS for Infinite, Ace is SS.
