best thing i reckon would be a couple of teleporters
Find a scroll or something to activate them where u want them (say 2 max)
and that way u could drop one next to a reliable food source and another on the later levels to get u back and forth.
You can use it to... attack enemys? did u come up with that reply all on your own or did u have to ask your mum what to say ? Of course u can kill enemies with it - u not going to shave with it,r you :) anyway i got the sword and even though i used it - i just throught it wasnt worth all the hazzle...
I went back and got this sword but yet never seen any real potential from it.
I had my fighter carrying it and i still ended up using magic to kill most of monsters.
My view is - this weapon is not needed and is more of a red herring that anything else.
