Negative Armor Penalty Increases Movement Points

[Shredded Cheddar]

So I was going through some failed ironman characters to look at gear, stats, feats etc. and while I was messing around with these characters I noticed two things.

The first thing was that having on over 100% armor penalty put my stealth skill into the negatives, which I found very odd since I assumed it capped at 0. This made me start messing around to see how armor penalty affected other things. I noticed on one character that his movement points were not what I expected. 6 Agi, 37 movement points without armor on. This made me very confused and so I started messing around with different starting characters and their agility points to see if the formula on the wiki (AGI-5)*3+30 was incorrect.

After making several different test characters with different agi I realized that the original character had nimble and thus a negative armor penalty and so he had bonus movement points. I checked with stealth, dodge, and evasion and it seemed that none of those skills were affected by negative armor penalty. Interesting stuff.

That's neat.  It must also be relatively new, perhaps introduced with all the new content, because a good while ago I had the same thought and found that a) armor penalty was capped at 95%, giving 1MP no matter what, and b) there was no "backwards overflow" with negative armor penalty giving bonus move/stealth.  That's a good find, though.

In my last few runs on experimental Armor Penalty was still capped at 95%, but going above that with helmet and boots etc. decreased my stealth into the negatives without changing the armor penalty numbers found on the combat stats screen. I also had 0 movement points even though I was at 95% penalty. Perhaps Styg is doing some ninja edits
