> The only portals on level 10 are summoning portals. I can summon monsters to fight with me, but I don't see how that gets me any closer to the light spell. I've checked my inventory and there's nothing there that would help. I'm on level 9 now, and I still haven't gotten the compass and light spells.

When you and your minions fight, are you doing a reasonably close reading of the actions during the battle? Some of the monsters you summon will have certain abilities beyond the usual brute strength. And you normally see these abilities exhibited during combat. It often boils down to who you choose as a companion (and sometimes crossing your fingers as well).

Incidentally, I'd recommend looking for a location spell before much longer. . . .
