Alright, I'm having a problem getting the correct AC for two sets of armor I have, maybe I'm missing something, but here it is.

Barbarians Breastplate 5 armor 2 dex +1 AC vs slashing Tumble: 10(+2 AC) +1 Deflection +1 Natural armor 5+2+2+1+1=21, right? But my AC is 22. It is counting the +1 AC vs slashing into the base AC I think, or maybe there's something I'm missing.

For some reason, it does take AC VS certain damage types into account on your character/inventory sheet. Has been like that forever, unsure wether it's a bug.

What you see is your AC VS slashing, though.

This is an annoying bug. Thank you for the report though, I'd thought we squashed this long ago. >_<

My advice on this one, is don't use the character sheets.

I learnt that in my arena days, they can be buggy at best.

The best place to get correct information on stats are in your combat log window.

So when it looks like your AC is bugged, will the engine use the correct numbers regardless?

Well my listed AC is 22, I haven't spent the time to test if that's actually the engine AC or not.

Yes. It should.
