Stealth - Stat


Stealth is the stat that affects if the enemy will detect you. Using a spell on a enemy or just attacking will automatically alert the enemy. Enemies can also alert nearby enemies, even if you have high stealth.

Calculation DetailsEdit


  • Effective stealth value S = stealth + modifiers (e.g. spyglass, equips, etc) - 1 for every 2 enemy tiers.
  • Base percentage of detection p = 0.78 S + 1 or 0.78 x 1.28 -S This means that if S falls below 0, you will get caught if you are in sight. Also, p can never fall below 0.


  • You have to be in sight under normal circumstances. E.g. Tranquility/time stop/sleep/etc has not been used.
  • If Distance/vision modifier ≥ 10-S, then p is cut in half. (You are half as likely to get caught if far enough away.)
  • If enemy is injured, then p becomes (1+p)/2. (Increases up to 50% asymptotically.)
  • Enemies have a stat called "Aware", which describes how much effort it takes to get away. Goes down by 1 per turn while out of sight, and may be set depending on circumstances. 0 is the maximum allowed Aware to be undetected.
  • Then there's an interative process. Here's where it depends on luck:
    • Generate a random number n.
      • If n < p:
        • Add 1 to "Aware" if Aware < 0 (provided S > 0).
        • Otherwise, Aware is set to Maxaware (6, 7, or 8 depending on difficulty level).
      • Repeat
    • In other words, the game gives the enemy multiple "dice rolls" to detect you if the first one succeeds.


  • Get out of sight.
  • If not in sight and Aware > -1:
    • p is reduced by 0.05 per distance.
    • Generate a random number n.
    • If either a) the enemy is unhurt, or b) n > p:
      • Reduce Aware by 1.
      • If Aware has become 0, you escape detection.
  • If Invisible stat is active, it always takes 2 turns to fully escape. Calming will also remove detection.

  • Using Invisibility Potion and Shadow Walk is basically 0% detection rate in which alerted enemies won't know where you are.
  • As enemies lose more health, they become more alert.
  • Having 18+ stealth will give a 0% detection rate.
  • Having -2 stealth will give you a 164-128% detection rate, generally everything is alerted.
  • Thief and Wizard starts out with leather shoes, adding 1 to their starting stealth.
  • In The Tower, enemies are more alerted in the higher tiers. They can eventually detect you even with Stealth 18+ because every other loop counters 1 stealth.
