Will someone explain THIS to me? (200kb worth of images)

[Rataxes]

Both pics are taken at the same time, I just don't see how the 4+9=13 MISS is logically possible when my THAC0 is -1

Also, could someone explain just what the number after 4 is? I know that the 4 is the rolled 1d20 number, but what the hell does +9 mean?

New question on topic. I just found out that his THAC0 looks rather fishy as well. As a lvl 9 Kensai with, at the moment, 22 str and Grand Mastery (patched) with a +1 Katana, I should get 3 + 4 + 3 + 1 = +11 THAC0 bonus to modify my base, which is 12. 12 - 11 = 1, not -1. Where does that extra +2 THAC0 come from? I also noticed that my max dmg is +2 higher than it is supposed to be.

Don't add the number to both your THACO and the to-hit roll, only add/substract it from/to one or the other and it should work out.

Your base THACO is 12 and you have +9 to hit with your main hand.

4+9 = 13 and it's a miss

So the Amnish Guard must have an armour class of -2

Thus requiring a 14 to hit with your main hand (minimum D20 roll of 5, plus 9 to hit with main hand)

[Rataxes]

Eh, how can it be a +9 bonus? I got +4 from 22 str, +3 from the lvl 9 Kensai kit bonus, +3 from GM in Katanas and +1 from the Katana itself. That's +11. I guess if he has -2 AC you could add it and get +9, but then I will have accounted for his AC twice in the same calculation, surely that's not the way it's done?

I also had that mysterious hidden +2 THAC0 bonus, it was not a display bug since I checked it's existence with SK and they were indeed there on the Effects tag.

Isn't your chance to hit on a d20 your THAC0 - Target's AC? Now that would be either

-1 - (-2) = 1

or if we assume that that hidden bonus doesn't really apply

1 - (-2) = 3

A roll of 4 should've scored a hit in either case.

Your explaination does makes sense in this particular case, but it doesn't fit in with anything I have read, experienced, or know about THAC0 and AC.

[drewal]

But there you are using your adjusted THACO of -1 or 1.

In that case, you would not add 9/11 to the to hit roll, thus that roll would be 4 - hitting an AC of -5 if you have a THACO of -1 or AC of -3 if you have a THACO of 1.

Base THACO 12
Minus 4 for Strength
Minus 3 for Grand Mastery
Minus 1 for Katana
Minus 1 for Kensai as (+9) is shown on your to hit rolls - this may be -3 as shown on your player's screen, but that bonus is not translating to your to hit rolls.

Equals THACO of 3

Though that is not what appears on your player screen, that is what your to hit rolls are using - a THACO of 3.

Thus, if you roll 4 to hit, you will hit anything with an AC as low as -1 but miss everything with -2 or lower.

Thus the guard must have an AC of -2 (probably 0 or 1 for armour plus shield/dexterity bonus)

If your THACO is indeed -1, then a 4 roll would miss anything with an AC of -4 or less; in that case the guard must have base AC of 0 and -4 for dexterity/shield.

[Rataxes]

I checked with IE and those Mercenaries of Riatvin has a max of -2 AC (if they actually get their dex bonus added on top of their Base AC, otherwise 2)

Either way, none of this makes sense. If I am to believe that my THAC0 really was displayed correctly, then that mercenary should've had to have at least -5 AC to avoid being hit on a roll of 4. If it was not displayed correctly, and I in fact only had THAC0 1. Then he his minimum AC should've been -3 to avoid the blow. If I only have a +9 bonus, which you imply, then he would still need an AC of -1, which he shouldn't have.

Then there's just a FACT that my THAC0 bonus should be 4 + 3 + 3 + 1 = 11
No matter how one twists and turns around everything else, the above must be true. Or else my game is just buggy.

If your main Hand To-Hit-Armor-Class-0 is -1, you'll need to roll -1 or higher to hit someone with AC 0 ( with the exception of a natural 1 ).
So if the guard has an AC of -2, you'd need a roll of 1 or higher, basically anything except a natural -1- would hit the guy.
