Fun thought experiment

[sox7d]

You're locked in a room with a toilet, unlimited food, immortality and a computer that only runs the first three expansions of EQ. However, you're the only one on the server.

You can't 2-box, but you can have multiple characters.
No hacks, but you can use exploits.

Given an infinite amount of time, what do you think one player is capable of(Hardest mobs/best gear) in Norrath and how would it go down?
