I am out of practice when it comes to building.
Hopefully some of you more savvy types can help this has-been.
Checklist:
-Must be fast! Whether by magic or class ability..
-Must be powerful! Able to solo all bosses except for the White Dragon
-Must be able to carry enough loot! Strength need not be sky-high, but hauling capability is required. Not opposed to polymorphing to this end..
-Good defensive capabilities! Whether by invisibility or high AC, Hips! anything one can think of that can be used to stay alive.
The RP concept is undecided, so the options as of right now are quite flexible.
Arcane, Warlock, Melee, Sneaky, Gish ... Anything you feel that meets the above requirements, throw it at me!
