A look of surprise and horror appears on Lord Surtur's face.
No!!! the Orb of Fate has lied to me! I have been misled!
Suddenly, Lord Surtur grasps his head and screams in agony, then dies.
Yay me!
That's my valkyrie finishing her quest. I cannot find a single source of levitation or water walking... so I had to very, very, very, very carefully make my moves there with all the lava and narrow passages.
In the tiles mode the red lava is pulsing with every refresh... very painful to look at, and also very scary since I might just step into lava again.
But at -13 AC, 154 HP and +5 Excaliur in my hands, Lord Surtur could do little else other than fleeing upstairs. (I had teleportis + ring of teleport control, but I am afraid to use it... if I chose a square already occupied it will teleport me to a random location which is probably filled with lava.)
Finally on Home4 I managed to zap him with my wand of sleep... then one hit and he's dead.
And since he fled 3 times, I don't need to tread all those lava to get back outside too!
Yay!
But it remains that I have no means to cross water... I managed Medusa by 2 scrolls of Earth and 2 wands of cold, but for the castle moat I have nothing. I also used my only magic lamp earlier for a silver dragon scale mail (4 huge barracks and I got BoH from Sokoban). Medusa level gave me a pair of fumbling boots and shield of reflection.
