Hello, everyone. As per title, I'd like to know some specific stuff about one of my favourite PC games from my childhood! (a lot of questions were answered 25+ years ago by that very useful "Free Hand" app, like the numbers behind the "increases", "strongly increases" and "very strongly increases" upgrades...)
so: is it possible to drop a suit of armor (like ring mail) with the poison resistance ability, in the first part of the game? I mean the mines. Because I remember getting a similar one several times, but I also remember that it was always the same, an "Enchanted Suit of Ring Mail" with the standard "increases armor value" and always the "increases fire resistance"... So I always wondered if it was possible to drop one with poison immunity, too (getting one in the mines, in the very early game, would've been totally OP!)
my second question instead is about the second game, with a new weapon ability that said something like "enchanted against X" and then it could be undead, devils, elementals, dragons, wizards... and that's all, IIRC. but did that mean, exactly? What did that ability do?
Thanks for anybody replying to this!
