Level drain is a status effect that removes a number of levels from a creature. Though not inherently permanent, this effect is always configured to be permanent until cured. [1]

With the loss of levels comes the loss of most things that progress with levels, including Hit points, Attacks per round, THAC0, Saving throws, Thieving Abilities and spell slots.[4]

In addition, any passive modifiers of the following stats coming from equipment or permanent effects[5] are suppressed[6] until the original level is restored:

  • Saving throws
  • Spell slots
  • THAC0, except for the weapon's natural modifier
  • Thieving abilities

Temporary modifiers such as those that come from spells will also be suppressed if applied before Level drain, but they can be successfully reapplied afterwards.


Gameplay[edit | edit source]

  • A creature drained down below level 1 explodes and dies permanently.
  • Dying from reaching level ≤0 may destroy non-critical loot, like with the Disintegrate and Petrification effects or with overkill from Cold damage. Disabling Gore in game options will avoid this.
  • A Simulacrum, whose lowered level is implemented by a type of Level drain that ignores immunities, may have significantly worse saving throws than its creator. It is advised to boost it with spells if possible, to compensate for the loss from equipment and permanent passive bonus.
  • Dual-classed characters will only be affected by Level drain on their active class.
  • Experience can still be acquired even though the character sheet does not display it, but levelling up is impossible.
  • A sufficiently level drained creature can be subjected to spells that wouldn't otherwise affect it such as Death Spell, Sleep and other spell afflictions that no longer work after a certain level threshold.


Note: Level drain must not be confused with ability score drain, which relies on other status effects such as Intelligence bonus for Mind Flayers, Strength bonus for Wraith Spiders, etc. Things that cure or make a creature immune to Level drain don't work on ability score drain unless they also target that. For example, Greater Restoration should work in most cases but not Lesser Restoration.


Level-dependent spells and abilities[edit | edit source]

As noted in the gameplay section, level drain effects can be used to put enemies in range of spells and abilities whose effects take a creature's level/hit dice into consideration. Those spells and abilities are:

  • Aura of Despair (at Blackguard levels 15-19 enemies under level 9 suffer panic, no save, at Blackguard levels 20+ enemies under level 19 suffer panic, no save)
  • Chaos (enemies under level 5 get no save)
  • Cloudkill (targets ranging from levels 1-4 are slain and those of levels 5-6 save vs poison at -4 or are slain as well)
  • Color Spray (targets under level 5 are the only ones affected by this spell)
  • Command (enemies under level 6 get no save)
  • Deathblow/Greater Deathblow (enemies under level 11/under level 13 are slain, no save)
  • Death Spell (enemies under level 9 are slain, no save)
  • Holy Word (undead and evil enemies ranging from levels 1-3 are slain, those of levels 4-7 are stunned for 1 turn, those of levels 8-11 are slowed for 1 turn and get 75% spell failure, and those of levels 12+ are deafened for 1 turn, no save against any of these effects)
  • Prismatic Spray (targets under level 8 are blinded for 5 rounds, no save)
  • Sleep (targets under level 5 are the only ones affected by this spell)
  • Storm of Vengeance (enemies under level 9 are slain, no save)
