Compiled by Dylan O'Donnell 

<psmith@spod-central.org>.

This spoiler covers all intrinsics that may be granted by wearing rings,
other than the dragon resistances already dealt with in drgn-343.txt:
how to acquire them (in addition to their ring source), how to lose them,

acquired solely by experience level can be lost by being drained below
that level.
