Found this game again a couple of weeks back (after not seeing it for several years) and started playing it again; finally got around to actually killing Diablo and moving onto Nightmare difficulty. Problem is, I noticed something the other day; for some reason, all of my resistances are set -20 instead of 0. They are still boosted by the various magical properties of my armour, but they are all 20 less then they should be (when I take off all the armour, they all sit at -20). Was wondering if this is a regular occurrence, or, if something has gone awry, if there's anything I can do to fix it. It's bloody annoying taking that extra damage...

A character's (and your hireling's) starting resistances to fire, lightning, cold, and poison is dependant on the difficulty level of the game:

Normal: 0 to all resistances

Nightmare: -50 to all resistances

Hell: -100 to all resistances

Meaning that if you have an item(s) that increase our resistance to fire by +68:

In Normal your resistance will be 68%
In Nighmare your resistance will be 18%
In Hell your resistance will be -32%

Hope that helps...

Ah, so it is to do with the difficulty level. Yeah, that's exactly what I was looking for, cheers mate.
