Well, I've finished with that savegame. No buy, no loss, no wanderer scrolls. Just 5 griffin eggs and a carved coffin
The fight for Verona map indeed took 203 turns

it was boring as hell, until turn 197 when the remaining 67 devilfish started to be tricky and "wait". Archers's ice arrow saved the day. The rest of the game was lots of fun with quite a few challenges. Getting 30 mana for the first few time back was a close one (2 from rat meat, 3 from shrine, etc), I had to spend a lot of magic runes on Wisdom. Sacrifice was sold on Rusty Anchor but its map was inaccessible, I had to kite away Old Rotbox in Verona, it was also sold there. The carved coffin was also there but you can grab it without kiting him. For a long time I was barely able to cast one sacrifice per battle, the vampires were growing slowly. Mana spring was not for sale until Montero. Later, with more rage coming in, and Chaos Magic 2, it was much faster, I could get 30-50 vampires per battle in easy fights, and stocked up a lot to last through the game. I got the ancient vampires very late, because I had to clear the basement on Nameless, and there were 460 necromancers and 45 bone dragons versus my griffins. They became a full stack and a lot in reserve in a few battles, and sadly, it was too easy after that, so I quickly finished it instead of clearing everything. Gremlion was easy. K'hatu was tricky due to the gorgonuas, a vampire with mark of blood wouldn't survive a turn. Baal was a close one. They would have been easy if I got more levels (I was level 48 at the end) and the staff with -15% undead leadership... but easy is no fun, is it?
