Someone offered me 100 million gold for a script that would recall in, stealth into the labrynth collect arties, leave, recall home, drop off arties, and repeat.
I got about 3/4ths the way through before I started Screaming and gave up. Mintaur Scouts reveal you every time, Move command is a bitch, and its a LONG ass Rail. It would work 40% of the time, but the other 60% you would die, still needs some love....... Would require a peacing, ninjitsu, stealth character, possibly with magery.
The guy was willing to pay 100 mill from it, so i'd bet he was getting some decent items from the quest.
