Odds of Epic Weapon

[Khaleesi]

Depends on the epic/class.
Anything that doesn't involve a dragon or the planes(do any not?) is going to be significantly more convenient and will mostly be a time requirement camping lesser mobs up until the final steps.

However you would be surprised at the generosity of guilds and individuals.

Best thing to do is manage all the parts you can alone, but always seek advice.
Then when you reach the tough bits, come on the forums and ask for help.

Despite TMO's reputation, they are not above assisting you.
