Two things I've come to hate so far, playing a solo game:
1) Wolf packs. They come in groups of 4-7, never stop attacking, are kind of hard to run away from, and give very little gold upon defeat.
2) Ghosts, in the Marsh Cave. They proved to be my downfall on my first attempt (thankfully I had used a Tent just outside the cave) by virtue of their attacks causing paralysis and my poor solo Fighter not getting cured with any rapidity. The six-pack of Ghosts and Zombies (lol recolors) then just wore down my Fighter bit by bit, until they had taken away all 300 of his HP and my party perished. Sometimes, I miss FIR2 and HARM.
I'm about to fight the Wizards you guys. L11!
POST-WIZARDS CARNAGE REPORT: So I got really really lucky and only had to fight 3 Wizards. And I still just barely beat them. I started with a full 300 HP, and finished with 10. If I hadn't gotten the first attack on the last round, I would've died. Now it's back to Elfland to replenish some supplies and then up to fight my avatar.
