Fiend Hunter Calculator¶
Stages and Archive
Fiend Hunter now uses Stages (Easy — Challenge) and is fought once per week. Bosses from before that update used Levels and daily attacks; their data is kept here as an archive, including the daily Threshold Damage. From now on, the tool will serve as an archive of Bosses stats.
This is a calculator for Fiend Hunter Bosses stats.
Type the Boss name, Season Event or Property to open the stats for a specific Boss.
- Stage Bosses show a table with Stage,
HP and 
ATK / 
MATK for each of the 5 Stages. - Archived (Level) Bosses show 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
Each stat of a Stage Boss is the sum of two addends, each rounded separately:
\(\text{Value} = \displaystyle\sum_{i=1}^{2}{\text{round}\left[\text{Base}_i \cdot 1.1 \cdot \left(1 + (\text{Parameter}_{i} -1) \cdot \text{Rate}_i \cdot 0.01 \cdot \text{Parameter}_{i}^{\text{Slope}_{i}} \right)\right]}\)
- \(\text{Base}_i \rightarrow \text{Base Value}\)
- \(\text{Parameter}_1 \rightarrow \text{Number of the Stage, 1 — 5}\)
- \(\text{Parameter}_2 \rightarrow \text{Stage-specific parameter (resembles the old Boss Level)}\)
- \(\text{Rate}_i \rightarrow \text{Linear Growth Parameter}\)
- \(\text{Slope}_i \rightarrow \text{Scale Growth Parameter}\)
- 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 Stage.
- Challenge replaces the second addend with fixed values (about +9T HP and +5000 ATK / MATK).
- ATK / MATK in Easy Difficulty does not include the second addend.
Legacy (Level) Stat Formula
\(\text{Value} = \text{round}\left[\text{Base} \cdot 1.1 \cdot \left(1 + (\text{Level}-1) \cdot \text{Rate} \cdot 0.01 \cdot \text{Level}^\text{Slope} \cdot \text{Stage Ratio}\right)\right]\)
- \(\text{Base} \rightarrow \text{Base Value}\)
- \(\text{Level} \rightarrow \text{Boss Level}\)
- \(\text{Rate} \rightarrow \text{Initial Growth Parameter}\)
- \(\text{Slope} \rightarrow \text{Scale Growth Parameter}\)
-
\(\text{Stage Ratio} \rightarrow \text{Level Related Multiplier}\)
-
Rounding is the same as above.
- Boss had specific levels, after which a new Stage was applied. That could modify the final stat value, although for at least 11 hunts it had no impact.
