Would anyone care to explain the effects of armor? I see stats like "Hitpoints 8, armor class 1/2" I'm pretty sure when those hitpoints reach 0, I'll need to replace the armor. But when I'm in combat, what does the armor do? In particular, does it reduce the chance of me being hit (SHP, etc.), absorb hits that would otherwise come out of my SHP (coming out of its HP instead) or both? Or something else?
I've been replacing leather armor a lot lately. Would acquiring chainmail help - or would it simply take as much damage as the leather armor, lasting a bit longer (due to having more HP when new) but being far more expensive to replace? I.e. if I fight something that would currently chew up my leather armor, but wearing chainmail, is it going to chew up the chainmail?
Thanks for any info.
