ToME: the Tales of Maj'Eyal

You should not be forced to carry a useless item with nonzero encumbrance.

You especially should not be forced to carry one that can be confused with the similarly named orb of many ways and dump you in an annoying to navigate level that leaves you on (usually) the wrong continent.

This would all be solved if you could ditch the -- literally -- damned thing.

Or you can be cleer and catch alchemist on lie and make tower instead. Solves problem and causes less problems unless you are playing on insane or madness.
