The Laudanum is a Revengeance Mode-exclusive Pre-Hardmode accessory. When equipped, any time the player gets inflicted with the following debuffs, they will receive specific buffs and the duration of the "debuffs" will be doubled.

The following debuffs will be converted to net-positive effects while the player is afflicted by them:

  • Armor Crunch provides 15 defense.
  • Blackout cancels light reduction and gives +30 defense, +25% damage and +10% critical strike chance.
  • Broken Armor cancels defense penalty and gives +25% defense.
  • Chilled cancels movement penalty and provides 1.3x move speed.
  • Confused cancels reversed controls and gives +30 defense, +25% damage and +10% critical strike chance.
  • Darkness cancels light reduction and gives +15 defense, +10% damage and +5% critical strike chance.
  • Ichor gives +20 net defense.
  • Obstructed cancels vision obstruction and gives +50 defense, +50% damage and +25% critical strike chance.
  • Slow cancels movement penalty and provides 1.5x move speed.
  • War Cleave gives 10% damage reduction.
  • Weak gives +10% net melee damage, +10 net defense, and +20% net move speed.

Any Boss Treasure Bag in Revengeance Mode has a 1.67% chance of containing this accessory.

  • Equipping the Laudanum does not prevent the player from being immune to the converted debuffs. The Ankh Shield and any of its related accessories will still provide immunity to the debuffs converted by Laudanum, meaning the player will not receive the positive effects if they have both equipped.
  • All boss bags have a 5% chance of containing any of the three universal Revengeance accessories, the other two being Stress Pills and Heart of Darkness, and then a 1/3 roll is cast for which accessory is given. This results in a 1.67% chance to obtain any of the three accessories, however the player can never receive more than one at a time.


  • This accessory's appearance is based on the Laudanum from Darkest Dungeon.
    • In previous versions of the mod, this accessory made the player immune to the Horror debuff. This was likely also a reference to Darkest Dungeon, in which Laudanum purges the game's Horror effect.
  • Laudanum is an extract of Papaver somniferum latex containing approximately 10% powdered latex by weight. It is useful as an analgesic and antidiarrheal.
