Items in ADOM are subject to periodic destruction by various means. These range from intentional usage (eg. potions, scrolls) to destruction by monsters, to acts of divine malevolence. Item destruction is generally undesirable, although it may occasionally be used to remove cursed stuff or under other specific circumstances. Note that not all items are subject to destruction in the same manner: potions and scrolls, for example, are extremely vulnerable to all types of destruction; metal equipment, especially higher metal equipment, tends to be fairly resilient. Artifacts are immune to all normal forms of item destruction (but may be destroyed through a few select means). Item destruction can be reduced most generally by acquiring the Luck and Fate Smiles intrinsics and removing Cursing and Dooming. Cursed equipment also seems more likely to be destroyed than blessed equipment. Rusty equipment is more vulnerable. Chracter resistances and immunities seem to lower the chance of item destruction (in theory triple fire immunity should allow wear leather items in ToEF, assuming no curse or doom).
Types of Item Destruction Edit
PCs engulfed by fire, be it from a fireball trap, dragon breath, or persistent heat from the Tower of Eternal Flames are subject to item destruction. A spellbook exploding in a ball of fire — which can sometimes happen if the PC fails to learn a spell from it — tends to do huge fire damage to the inventory. Fire is capable of destroying nearly all items not made of higher metals, including scrolls, potions, bows, arrows, and iron equipment. Carrying a fireproof blanket will protect the inventory from fire damage; wearing a ring of ice will protect both the inventory and worn equipment.
Acid destruction typically comes from acid traps, acid vortices, or black dragons. Acid is capable of damaging most items in the PC's inventory; it has a quite high chance to destroy items of iron and weaker materials, and has a small chance to destroy mithril or even adamantium items. Scrolls and potions seem particularly likely to be destroyed by acid.
Water has the capacity to destroy items made out of paper, such as scrolls or books, and to rust metal items. No other items are damaged by water. Waterproof blankets will protect the inventory from such damage; hooded cloaks and cloaks of protection seem to protect worn items from being damaged by rain in the wilderness. Water damage can arise from swimming, rain, water traps, or water breath attacks.
If the PC is attacked by a powerful blast of cold, such as from an ice vortex or white dragon breath, then they will experience item destruction. Items damaged from cold seem to be restricted primarily to items damaged by water, namely books and scrolls, as well as potions. A ring of fire protects the inventory from cold damage. Note that cold bolts from ogre magus and the Chaos Archmage do not cause inventory damage; neither does traversing D:49.
Lightning damage results primarily from encounters with lightning vortices, lightning lizards, blue dragons, or self-electrocution with a lightning bolt spell or wand. Items affected by lightning are similar to those affected by fire.
PCs who fall from using a cursed climbing set, fall down the Rift, or are crushed by a falling door or ceiling trap will be subject to significant equipment damage. This damage tends to be localized to potions, scrolls, and arrows, primarily, although on occasion items made from iron, such as climbing sets may also experience some damage.
Rune Traps Edit
Exploding runes from doors are among the nastiest sources of item destruction. They often destroy worn equipment, particularly cloaks and items made from leather or iron.
Some monsters have the capacity to destroy worn items. Annihilators and eyes of destruction are able to destroy any non-artifact the PC is wearing, including higher metal items. Monsters with powerful melee attacks, notably berserker emperors and greater molochs seem to have the capacity to destroy worn pieces of armor, even higher metal ones such as red dragon scale mail. Rust monsters may rust any worn iron equipment, and can destroy rusty equipment. Gelatinous cubes will destroy any item that they step on; ochre jelly and gray ooze will damage metal weapons, up to and including adamantium. Fighting them barehanded will damage gauntlets; kicking them will damage boots, and persistently fighting these will eventually result in outright destruction of the equipment.
Divine Retribution Edit
If a PC attempts to pray or sacrifice on an altar of an extremely upset deity, they may receive the message "'*I* hearby punish thee, puny mortal!' Your inventory turns to dust." This results in the destruction of all worn items, regardless of metal or status, except artifacts. Also, if you kick an altar and cause it to shatter, deity will become enraged and destroy all your equipped items.
