I played a bit of Nethack today and stumbled across a scroll called LEP GEX VEN ZEA.
It’s fantastic! Upon reading the scroll the entire level map appears in your mind.
I made it through to the seventh level of the gnomish mines. For a while I thought I’d die of starvation as I had run out of edible food. Would have had to risk eating a corpse of one of the monster’s I slaughtered along the way.
I dragged along a coyote corpse just in case, but came across a wererat that attacked. No problem I thought, but then the wererat called up his other wererat buddies and they had me surrounded. Cast a few healing spells and faught like hell but it was not to be.
