Item destruction

Obsolete: This article refers to an aspect of the game which has been removed. It is retained for historical reference only.

Although the majority of the dangers you'll encounter while exploring the Dungeon simply try to reduce your HP or afflict you with status effects, some monsters and damage types also inflict item destruction. Although this won't kill you directly, losing critical consumable items can greatly reduce your odds of survival. Bear in mind that these attacks attempt to destroy every item in your inventory individually; carrying lots of useless scrolls, potions, or food will not reduce the chance of your useful items being affected!

Scrolls

Any time you suffer fire damage, there is a chance that your scrolls will be destroyed. The likelihood of this occurring decreases when your AC reduces the damage dealt. You can reduce this chance through the following means:

• The preservation or conservation intrinsics (90% reduction)
• The Hurl Hellfire and Ignite Blood demonspawn mutations (90% reduction)
• Wielding the Firestarter protects your scrolls
• Worshiping Jiyva (piety-based reduction)

Potions

Any time you suffer cold damage, there is a chance that your potions will be destroyed. The likelihood of this occurring decreases when your AC reduces the damage dealt. You can reduce this chance through the following means:

• The preservation or conservation intrinsics (90% reduction)
• The Passive Freeze and Icemail demonspawn mutations (90% reduction)
• Worshiping Jiyva (piety-based reduction)

Food

Any time you are hit by a giant spore explosion, there is a chance that your food will be destroyed. You can reduce this chance through the following means:

• The preservation or conservation intrinsics (90% reduction)
• Worshiping Jiyva (piety-based reduction)

Corrosion

Acid attacks don't destroy items, but they do cause corrosion, reducing item enchantment. Corrosion comes from two sources: striking a monster that has acidic flesh (which only affects your wielded item or gloves), and acid splashes (which affect all worn pieces of armour, but not your weapon).

If an item is corroded, it still has a chance to resist the corrosion based on its enchantment value. The greater the absolute value of an item's enchantment level, the better its odds of resisting.

Enchantment (+ or -)	Resist %
0	6%
1	18%
2	34%
3	58%
4	98%
5 or more	100%

Otherwise, the following methods reduce corrosion:

• The resist corrosion intrinsic (found on the amulet of resist corrosion and the cloak of preservation) gives you an additional 90% chance to resist corrosion.
• Dwarven items and crystal plate mail receive their own 80% resist chance.
• Artefacts are completely immune to corrosion.

History

• Item destruction for items on your inventory was entirely removed in 0.15.
• Prior to 0.17, jellies would destroy seen items by moving over them, even without worshipping Jiyva.
• Prior to 0.14, harpies had a unique food-destroying melee attack that only Jiyva-worship could defend against. Additionally, items on the floor could be destroyed by slimes moving over them.
• Prior to 0.13, damage reduction through AC had no impact on item destruction chance.
