Elite Spawn Increase
Elite Spawn Increase is a stat that raises the chance that a spawning enemy will be an elite instead of a normal enemy. You start at 1.0× and can increase it from any of the sources listed here. The relationship is linear: doubling the stat doubles your elite chance; 10× stat means 10× as many elites (on average).
There are two main reasons you'd want to increase your elite spawn chance:
- Elite enemies gives 10x more XP than a regular enemy when killed
- Elite enemies are 2x more likely to drop a chest when killed
Do note that it's not possible for all enemies to become Elite enemies. But it is for the vast majority of normal enemies you see throughout the stages.
For any enemy type that can be elite:
So at 1.0× stat, the chance per eligible spawn is $0.006 = 0.6\%$. The only fixed number in the formula is that 0.006 base at 1.0× stat.
EliteSpawnIncrease is a direct multiplier on that chance. Examples:

Formula
For any enemy type that can be elite:
$$\text{eliteChance} = \text{EliteSpawnIncrease} \times 0.006$$
So at 1.0× stat, the chance per eligible spawn is $0.006 = 0.6\%$. The only fixed number in the formula is that 0.006 base at 1.0× stat.
How the stat affects elite spawns
EliteSpawnIncrease is a direct multiplier on that chance. Examples:
So: 2× stat ⇒ 2× elite rate, 10× stat ⇒ 10× elite rate.
