Miscellaneous intrinsics in NetHack 3.4
Compiled by Dylan O'Donnell <psmith@spod-central.org>.

This spoiler covers all the intrinsics that are neither dragon resistances
(see drgn-343.txt) nor conferred by wearing rings (see rint-343.txt). It
does not cover statuses (confusion, hallucination, etc); the dividing line
is sometimes blurry, but as a general rule of thumb if it appears on the
status line it's a status, not an intrinsic. Note that, as a general rule,
any intrinsics acquired solely by experience level can be lost by being
drained below that level.

amphibiousness
  acquired by
    Polymorphing into a floating eye, water elemental, newt, (baby)
    crocodile, or any ;.

    You can enter water safely.

  acquired by
    Wearing the Eyes of the Overworld (Monk Quest Artifact).

blinding resistance
  acquired by
    Wielding Sunsword (light-based only).

    magic traps, and expensive cameras.
    Physical-based resistance protects against the blinding attack of
    ravens and cobras, but not against dust vortices or thrown cream pies.
    Note that being blinded already, or being polymorphed into a form
    that has no eyes, is an absolute defence against blinding.

clairvoyance
  acquired by
    Wearing a cornuthaum as a Wizard.
    Donating between 200*XL and (400*XL)-1 zorkmids, more than 1/3 your

    Wounded legs do not reduce your carrying capacity.
    No ill effects from descending stairs when encumbered, fumbling or
