While you possess disintegration resistance, the breath attack of a black dragon, and the wide-angle disintegration beam of an angry god have no effect. Disintegration also protects your shield, cloak, body armor, and shirt from the effects of the former.
Disintegration resistance can only be obtained through the following methods:
- Eating the corpse or tin of a black dragon (100% chance) or the Chromatic Dragon (1⁄6 or ~17% chance)
- Wearing black dragon scales or black dragon scale mail.
The most obvious reason to obtain disintegration resistance is to prevent instadeaths from disintegration. In practice, though, this can be achieved by obtaining reflection (which also completely protects against disintegration breath) and being careful not to anger the gods. However, it is still a good idea to seek the intrinsic if possible, in case a black dragon attacks you while you are nurse dancing or polymorphing yourself.
- You feel very firm.
- You gained disintegration resistance from eating an appropriate corpse.
- You feel totally together, man.
- As above, while hallucinating.
