This spoiler covers all intrinsics that may be granted by wearing rings, other than the dragon resistances already dealt with in drgn-331.html: how to acquire them (in addition to their ring source), how to lose them, and what effects they have. Note that, as a general rule, any intrinsics acquired solely by experience level can be lost by being drained below that level.
