Distinguish User Level, hero unlock requirements and Growth-system levels before spending progression materials.
What increases User Level?
The User EXP item description says: “Experience used to increase your User Level.” Stage pages expose stored Clear EXP source values for individual steps. Those values identify a saved reward field; they do not measure EXP per hour, account for offline caps or establish the fastest leveling route.
User Level and hero unlock requirements
Hero pages list account-level requirements separately from required unlock items. Check both before choosing a character. Equipment level limits and skill-level records describe other requirements; do not treat them as your User Level or assume that raising one system unlocks every other system.
Training Ground and Ability Unlock levels
The developer FAQ states: “Higher levels increase the probability of higher ranks appearing.” This refers to Training Ground and Ability Unlock. It does not give numeric probabilities or prove that the highest available upgrade is the best use of resources. The Growth guide explains their different materials and presets.
