WTF is a one time drop?
Oki - in brief, you kill the monster (either alone or in party) and if you are of the required level, you get the item placed in your pack as the mob dies. You dont get the item if you cannot use it, and you dont get the item if it has already dropped for you (the one-time part), but when the mob dies, all people in the party of the correct level or higher, who can use it, will get it.
An assumption here is that most of the named mobs 25th+ have such drops, and if you kill them when they are yellow to you (estimate) you might pick up a drop if you are the right class - so any more ya find, message me the details. Most of what we have here is taken from board somewhere, so thanks to Absalom Serraitus creating the thread i got this lot from.
