Analyze an encounter with two CR 3 monsters (450 XP each) and one CR 5 monster (1800 XP) for a party of 4 players at level 5.

The encounter difficulty is Medium. The Adjusted XP is 2700, with a Moderate TPK risk. To reach a Hard tier, consider adding more creatures or increasing the monster XP.

What is the multiplier for an encounter with 6 monsters?

The encounter multiplier for 6 creatures is 2.0.

What are the XP thresholds for a party of 5 players at level 10?

For a level 10 party of 5, the thresholds are: Easy up to 1200 XP, Medium up to 2400 XP, Hard up to 3600 XP, and anything above 3600 XP is Deadly.

The tool 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.
