The Iron man save is still present, but I lost all my progress in the ancient skeleton level, items gotten, experience, everything, from what I can tell. I am going to avoid using the lightning disk spell from now on.
Possible bug: I am taking on and off a ring that has "Increases Attack Rating by 5". But I cannot see any changes in the level screen. Does "attack rating" not affect wands?
Minor bug, three skeleton archers stuck behind a bookshelf:
A golden goblin, together with some rings that gave extra poison damage, health/mana on kill, and some other properties, yielded a very good ring that gave extra damage of other types and +3 mana on kill. Combined with level 3 "Purifying circle" and other items that give extra mana and health on kill (I am still carrying a book of that which I cannot read yet, I did not pick up yet another book like in the lost progress before the game froze previously), I can remote-clear several open areas rather easily in this level.
Regrettably, I lost my Iron man run. I realized too late that I was up against a boss in the "Breeding Grounds 1", in a panic I retreated into unknown territory, and ended up stuck in a corner. The game felt really easy right before I died, since I dealt something like 16-22 damage per wand shot (with items that gave extra damage per shot), and I believe I could have comfortably deal with that boss if I had not in a panic foolishly retreated into enemy territory - my inventory was full of potions and I also had the "Haste" spell for kiting or escaping. I would not mind it at all if bosses were made much clearer, because the game for some portions changes between "killing mobs that are no danger at all if you play at least a little bit well" to "need to kite, maybe retreat, maybe think how to deal with it, refill potions, can very much die" bosses. And even then, many bosses are not really that dangerous.
