Caves Of Qud Wiki

Items in Qud can occasionally be found possessing one or more enhancements, such as weight reduction, additional elemental damage, or providing extra protection. Those pre-modded items are relatively uncommon to find, but with Tinkering you can add these modifications to your own weapons and armor, provided you have learned the schematics from a data disk, Water Ritual or relevant Cybernetic implant.

  • See the page on Relic for list of unique mods used by Historical Relics

You can modify something up to three times, items that already have mods still count toward the limit. Tinkering requires 2 bits, first bits are based on the Tinkering Tier of the mod and the second bits are based on the level of the item being modified. The level of the second bits increases with each modification but the first does not change.

Note that the tinkering tier listed here is different from the levels used for tinkering skills; Tinkering I allows tier 1-3, Tinkering II allows tier 4-6, and Tinkering III is needed for modifications of tiers 7-8.

Item Status Effects[]

Apply to almost any item. Those are generally added to items as a side-effect of combat. They are not mods, but are included here because they can be easily mistaken for mods.

Name Effect Value Change
Bloody Item is covered in blood. Can affect items lying on the ground, if Critical Hits happen nearby; items can be washed by pouring a dram of water on them or by dropping them in water -
Liquid Item is covered in Liquid. Similar to bloody, this can modify any item when applied, poured on, or submerged in a certain liquid. Some liquid such as acid can physically affect the weapon, while some does nothing at all in particular -
Broken Item is no longer functional and must be repaired. Greatly reduces value; can be caused by failed artifact identification attempt. Fixed with Repair, repair services or Fix-It Spray Foam 1%
Cracked Reduced AV. Effect of attacks on worn equipment by monsters that can damage items. (Knollworm, Segmented Mirthworm, etc.) Effect is removed automatically after certain number of turns. none at -1 AV, 50% at -2 AV, 33% at -3 AV, 25% at -4 AV, etc.
Flaming The item is on fire and increases the temperature around it, even when picked up. It will soon be destroyed. Pour water on it or attempt to extinguish it by beating the fire out via the interaction menu. -
Rusted Item is no longer functional and must be repaired. Greatly reduces value; can be applied to any metal item (even equipped or in inventory) by certain creatures. Repeated rusting of the same object can destroy it entirely. Regular repairing removes this state. 1%


  • While you cannot apply the same mod to an item multiple times via tinkering, most mods with an X value in them, such as Electrified (X), will get a higher value if you mod the enhancement onto a higher-quality piece of equipment.
  • Mods with randomized values like Spring-Loaded can be maximized by retrying with Precognition. Additionally, an item can have only three mods applied to it in total; and each one you apply increases the cost of the next.
  • The cost (in tinkering bits) of modding an item depends on its value. You can add multiple mods to an item, but each successive mod will be more expensive than the previous.
