Progression priority list
This is a system priority list, not a fabricated hero ranking. Public sources confirm the systems below but do not publish dependable unit-by-unit stats.
All stages
Soldiers
Your repeatable frontline and wave-clearing core. Prioritize a dependable fielded squad before spreading resources across every new roll.

Base Defenses
Reliable defenses protect your economy while your army handles the wave. Upgrade bottlenecks instead of improving every structure evenly.

Heroes
Heroes are high-impact rolls, but chasing them before your economy and soldiers are stable can slow progression.
Read the priority guide →How we rank priorities
We look at progression dependency: what keeps earning resources, what prevents wave failure and what becomes efficient only after the foundation works. When public hero or soldier stats become verifiable, named-unit rankings can be added without replacing this core framework.
