The following note on the main article page has been disputed in a problem report and requires in-game verification:

If you are evil: there are 2 Heroic guards standing at the door of Gnollslayers. They do NOT see mage-casted invisibility or Scout stealth, but WILL see through the racial stealth of half-elves. If you cannot invis, by the time you can use a totem to invis they will be grey to you. Also be aware that as of LU38, searching an object, such as a chest to get a book, is a harvesting skill. It has a 2 second cast and it breaks invis!
