Magicbane can help wizards with their quest too, and they can get it as a gift from their deity. Since the Dark one has an attack that can curse inventory items, he cannot harm a wizard weilding magicbane.

And then the wizard could stand on the stairs and beat the Dark one to pulp.

Both wizards and healers should consider alt-weaponing the other's special weapon. (Requires a wish for a wizard and just of lot of blood on the stone for a healer.)

Magicbane gives the healer MR (though they can easily wear a dragon hide out of their quest), engraving, and bonus spell points when beating spell casting demons or L's slowly over the head with it. (The staff has no special bonus against these types and the curse deflection is extra handy.)

Wizards start with skill in the quarterstaff, it's one of the few artifacts they can get to expert in, and it provides level drain resistance which they usually have a hard time with. (Especially when leading a large group of wraiths away from their resting places.)

Of course in the hands of a Rogue, Magicbane becomes the nightmare blade. (Sleep a Minotaur, tap him with Magicbane until he gets scared in his sleep, then toss 4 daggers into his backside.)

I've never been too fond of healers, but now I feel like I should give them a try. But magicbane makes everything look too easy, and I fear it might have the same side effects as 'Felix Felicis' from Harry potter (if you don't know what that is, look it up. You might get LUCKY and find the answer in the first go.)

If you're no fan of Felix Felicis, cast "to flesh" at your own character. ;-)

Does it turn luckstones into meat? Because the possibility makes me not want to try it.

There's an easy way to find out...
