FAQ
Questions Encounter Difficulty Calculator owners ask.
- 01
How is the encounter difficulty determined?
The capability calculates 'Adjusted XP' by summing the base XP of all monsters (multiplied by their count) and then applying an encounter multiplier based on the total number of creatures. This value is compared against thresholds for your specific party level and size.
- 02
What does 'TPK Risk' mean?
Total Party Kill (TPK) risk is an estimation of the likelihood that all player characters will be defeated. It increases as the encounter's Adjusted XP moves into the 'Deadly' range.
- 03
Can I use this for both D&D 5e and Pathfinder 2e?
Yes, the calculation engine is designed to work with the XP-based systems used in both D&D 5e and PF2e.
