Duriel Quest

[JustAGuy]

If you have two characters, one sitting in town and the other questing, both partied, and you complete a quest, the one character that is sitting in town doing nothing gets credit for its completion. The only time that he doesn't get credit for it is if the character that is questing has already completed the quest before, in which case the character in town would get the old "you cannot complete this quest..." message. In that case, the town-sitter would have to get the last hit on end bosses, or be present at the death of certain item dropping bosses. Also, you have to be in the same act to get quest credit.

Take, for example, the hellforge quest and these criteria:
1. The town-sitter (townie) created or joined a game in which the quest was open.
2. A second character joined and he had already completed the quest in a previous game.
3. The two characters partied together.

Hepphy would only drop the hellforge hammer if the town-sitter was present for his death, but the townie does not need to get the final blow. But, if the town-sitter stays in town at the moment of Hephasto's death, the hammer will not drop and the town-sitter will get the "cannot complete quest" message.

For act bosses, the town-sitter must get the final blow in order to complete the quest. So, if you're carrying a character along, be sure not to exit or unparty before you get the credit for beating the boss...

So, with this in mind, level 1 characters can be carried all the way to Hell act 5. It's not necessarily a good idea to do so, because of the added difficulty of having more people in the game and having one of those people do absolutely nothing... The only place a level 1 cannot go are the worldstone chambers. Since they can't get credit for the ancient's quest at level 1, they are disallowed from entering the chamber via way point or town portal.

I have a couple of level 1 characters that have access to all way points in all acts (except for the worldstone way points) but whom have never faced an end of act boss. Good thing too, since they're only level 1 and they would be clobbered instantly. It's kind of funny having a character that has all of the quests completed (except for ancients and imbue quest) and has all quest rewards but yet is level 1. A level 1 with 12 skill points 60 extra life and 30 to all resistances. That'd make starting a new character easier, eh?
