Alternately (or additionally) there could be an "Obelisk of Revealing" which would have one of the effects listed above. Maybe it could even allow you to see invisible enemies from farther away...
I am all for a obelisk of revealing or even a cartographer in town who will fully reveal a already visited dungeon floor for a hefty price amount like ten to thirty gold pieces (or at a high-range price for world level). Especially for the levels when there is that ONE ROOM you cannot find that contains the unique / boss monster or item, would be worth the money to unveil the whole floor.
