Entry Requirements


Underling Mechanics

The amount of $HERO earned per run depends on your Hero’s ATK stat. A higher ATK = greater rewards.

ATK is influenced by:

  • Hero Level – Leveling up increases base ATK

  • Equipped Weapon – Both weapon stats and sharpness contribute to ATK

Each Underling battle lasts 6 hours. While Heroes are locked in during this time, $HERO earnings can be claimed at any point throughout the duration.


Earnings Calculations

1. Max $HERO/day

The upper limit of what your Hero can earn per day, based on ATK: maxHeroPerDay = (ATK × 400) / (20 + Hero Level)

2. Base $HERO/day

Guaranteed 80% of your max, regardless of weapon sharpness: baseHeroPerDay = 0.8 × maxHeroPerDay

3. Sharpness Bonus

Up to 20% bonus, scaled by your weapon’s current sharpness: bonusHeroPerDay = 0.2 × maxHeroPerDay × (Sharpness / MaxSharpness)

4. Effective $HERO/day

Your actual daily reward is the sum of base + bonus + daily flat bonus (e.g. 50): effectiveHeroPerDay = 50 + baseHeroPerDay + bonusHeroPerDay


🧪 Example Calculation

Inputs:

  • Damage: 210

  • Hero Level: 10

  • Sharpness: 5/10

Step-by-step:

maxHeroPerDay = (210 × 400) / (20 + 10) = 2800  
base = 0.8 × 2800 = 2240  
bonus = 0.2 × 2800 × 0.5 = 280  
total = 2240 + 280 = 2520 $HERO/day

➡️ Final Earnings: 2520 $HERO/day
