At first glance, the first day showed a very good setup: a hidden stash of nagas and giants behind a simple guard, boots that remove the movement penalty on difficult terrain, and Gurnisson, on level 2, gained Earth magic and dispelled the despair spell near the hidden stash of mages. Later, I found 2 conservatories with 3 angels each :(, and a Greater Archdevil - 18.
I reached the center, where I obtained a hat with +10 knowledge and a hive with 6 vipers. I didn't even have time to grab the golden bow on the respawn point, and I lost the ballista. Even with a mana advantage due to weak stats (I didn't find any artifacts that boosted combat stats), defeat was inevitable.
Thank you for your time!
