If you have a melee combat buff that causes a visual effect, such as from a confuse monster effect (or other ones in variants, such as the burning hands spell) it should be readily visible in either the #seeweapon ()) command if you are non-blind as e.g. “a - a dagger (weapon in hand). Your hands are glowing red.” or in the #attributes (ctrl-x) command as e.g. “You are able to confuse monsters that you hit.”, or both. Possibly, if implementing both, the effect should not be provided in #attributes, but only in feedback from enlightenment.

There should be more types of skeletal monsters in the game beyond the one-level-wonder ordinary skeletons (and technically liches). Particularly, there should be skeleton dragons, whose scale mail makes you inediate (not just slow digesting).

More types of skeletons appearing in more places would also allow for a “bone” item to be dropped, which various interesting things could be done with.
