Knightica: How to Scale to Endless 25 on Insane Difficulty

To clear Endless 25 on Insane difficulty in Knightica, you must build an infinite scaling loop rather than relying on flat stats or pure defense. Secure passive income early, hoard duplication resources for your top scaling artifacts, and cluster your primary damage dealers in central board positions to outpace rising enemy health and damage pools.

Build Priorities for Infinite Scaling

Insane difficulty scaling will quickly outpace linear defensive builds. To hit infinite power, pivot toward artifacts that offer multiplicative synergies and save early resources to afford high-cost mid-game upgrades.

Multiplicative Artifact Focus

Avoid flat damage items early, as they rapidly lose value in late waves. Prioritize artifacts that scale exponentially based on combat triggers:

Attack Speed Modifiers: Increase attack frequency to trigger hit-based secondary effects as often as possible.
Proc-Coefficient Boosters: Raise the activation chance of high-tier secondary item effects on every attack.
Health-to-Damage Converters: Turn your health upgrades directly into scalable offensive power.

Item Duplication Strategy

Duplication mechanics—whether from specific artifacts or hero abilities—are essential to breaking standard scaling caps.

Hold high-tier duplicators: Save duplication resources for high-tier artifacts that offer percentage-based or scaling returns rather than spending them on low-tier baseline items.
Target exponential modifiers: Duplicating an item that converts stats (such as health to damage) multiplies its output across your entire build, creating a rapid growth curve rather than a flat addition.

Board Positioning and Unit Layout

Physical placement on the board dictates how effectively your units share buffs and survive heavy waves.

Position Role	Placement Strategy	Primary Function
Central Anchor	Center of the unit formation	Holds vital scaling items and receives overlapping area buffs
Buffer Perimeter	Outer edges facing enemy spawns	Soaks incoming damage to protect core units
Ranged Backline	Direct line of sight to main spawn paths	Maintains continuous attack uptime to trigger proc effects

Resource Management and Mid-Game Adjustments

If enemy health bars stop moving quickly during a wave, your scaling rate has fallen behind enemy stat growth. Use these adjustments to clear bottlenecks:

Establish Passive Income Early: Invest in early passive income generators so you have enough gold to afford pivotal scaling items when shop costs rise.
Pivot Away From Pure Defense: If clearing waves becomes difficult, stop buying health-only upgrades and redirect resources entirely into damage multipliers.
Clear Board Space: Sell low-efficiency units that do not contribute to your core scaling loop to free up board tiles for essential multiplicative artifacts.
