This covers all the intrinsics that are neither dragon resistances (see drgn-340.html) or conferred by wearing rings (see rint-340.html). 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.
