This is a calculator for Fiend Hunter Bosses stats and threshold damage.
Type the Boss name, Season Event or Property to open the stats for a specific Boss.
Table includes Level, 
HP, 
ATK / 
MATK and the Daily Threshold Damage (the consistent score required each day from Day 1 to successfully defeat that level by the final day).
Displayed Level amount can be changed, from 1 to 100 (default — 25).
If you are looking for raw Fiend parameters instead, refer to this data file instead.

Stat Formula & Details
\(\text{Value} = \text{round}\left[\text{Base} \cdot 1.1 \cdot \left(1 + (\text{Level}-1) \cdot \text{Rate} \cdot 0.01 \cdot \text{Level}^\text{Slope} \cdot \text{Stage Ratio}\right)\right]\)
- \(\text{Base} \rightarrow \text{Base Value}\)
- \(\text{Level} \rightarrow \text{Boss Level}\)
- \(\text{Rate} \rightarrow \text{Initial Growth Parameter}\)
- \(\text{Slope} \rightarrow \text{Scale Growth Parameter}\)
- \(\text{Stage Ratio} \rightarrow \text{Level Related Multiplier}\)
- Rounding in the formula works as follows:
- For HP, rounding down to 3 significant figures is applied.
- For ATK and MATK, rounding to the nearest integer is applied instead, with 0.5 being rounded down.
- For
- Parameters do not change with level. However, boss has specific levels, after which a new Stage is applied. That can modify the final stat value, although recently (for at least 11 hunts) it has no impact.
