Miscellaneous intrinsics in NetHack 3.4
Compiled by Dylan O'Donnell <>.

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.

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

    engraving with a wand of lightning, failed use of a crystal ball,
    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.

    that has no eyes, is an absolute defence against blinding.
