Version 0.31: This article is up to date for the latest stable release of Dungeon Crawl Stone Soup.

The threat level of a monster is a rough indicator of how difficult/dangerous a monster is. This information is accessible through the monster list at the right side of the screen, or in the monster's descriptions. When Ashenzari detects a monster, you'll see their threat level (but not the type of monster). Threat is also used for a few other mechanics throughout the game (such as tension).

The game defines four tiers of threat:

Threat level Monster's name Description
Trivial Dark grey Minor
Easy Light grey Low
Tough Yellow High
Nasty Light red Lethal


Threat is based off two factors: a monster's XP value, and the player's current experience points.

Tension = Monster's XP points / ( 1 + sqrt(Player's XP points / 30))
If Tension is less than 1, Threat = Trivial
Else if Tension is less than 6, Threat = Easy
Else if Tension is less than 33, Threat = Tough
Else, Threat = Nasty

This means that for any species with an experience aptitude of 0, a monster that gives 5582 XP or more will always be labeled nasty.


  • Prior to 0.31, the threat descriptors were as follows:
Threat level Monster's name Description
Trivial Dark grey "It looks harmless."
Easy Light grey "It looks easy."
Tough Yellow "It looks dangerous."
Nasty Light red "It looks extremely dangerous."
