Hi,

Some of my characters now have negative THAC0's and negative saving throws.
Can I understand a negative THAC0 of let's say -1 as a THAC-1 of 0 ?
And what effect have negative saving throws ?

Thanks.

THACO is a name (label, variable) whose value is 0, -25,
whatever.

A negative Thac0 means that to hit an armour class of 0, you would need
to roll less than one. Since one is an automatic miss, your character's
will hit 95% of the time against any enemy with an armour class of 0.
If they had an armour class of -10, then the negative thaco works to
overcome this.

You can't fail on anything but a 1.

Which happens 6 times out of 10

Yes, thanks and how ? Like the way I said ? (THAC0 of let's say -1 as a THAC-1
of 0)

Yes, but that's with a saving throw of 0 as well, no ? So what's the ADVANTAGE
of negative saving throws ?

Also, the negatives on saving throws help to combat penalties you get from
enemies' spells. Greater Malison springs to mind.

Meaning that it's the minimum value you need to roll on a 20-sided dice to
hit an enemy of Armour Class (AC) 0. To find out what you need in order to
hit a particular enemy, you subtract their AC from the score, so that if
your THAC0 is -1 and an enemy's AC is -5, you need -1 minus -5, which is 4.
So you were correct in saying that, at THAC0 -1, you need 0 to hit AC -1.

Bear in mind that, while this appears to mean that you'd hit such a
character every time, rolling a 1 will always result in a critical miss (you
miss your target completely, and are off-balance and have to skip a round
before attacking again), while rolling a 20 always gives a critical hit (you
hit the target regardless of its armour class, and unless it is protected by
a helmet or equivalent, your hit inflicts double damage).

In the interest of clarity, a THAC0 of -1 IS in fact a THAC-3 of 2... the
example if THAC-1 being 0 is, correct, technically, except a "1" will miss
every time anyway. Just so I'm really, really clear here, a THAC0 of -1 =
THAC-10 of 9.

By D&D rules a roll of 1 always fails/misses no matter what.

Your THAC0 (To Hit Armor Class 0) is just that; the you/the computer must
roll in order for your character to hit something with an armor class of
zero. From the THAC0, you subtract (yes, you subtract) the AC of the
creature you are attempting to hit. So, if you have a THAC0 of 20, and are
attempting to hit something with an AC of 10, you need to roll a 10 or
higher. If you have a THAC0 of, say, -5, and your target has an AC of -10,
you have to roll a 5 or higher. But, (and there's ALWAYS a but,) if you
roll a 1, it's always a miss, and a 20 always hits.
(The computer simulates the roll. You can tell it to display this in
the options menu.)
Saving Throws work somewhat simalarly. In order to save against a spell,
attack, whatever, you have to roll higher than your applied saving throw on
a 20 sided die. Makes it pretty easy when your saving throws are in the
negatives, huh? Penalties are sometimes applied to what you roll, though.
Hope this helps.

Spells like Greater Malison (+4 SS adjustment) and others which penalize
SS don't have as good effect.
I.E. -3 SS, Greater Malison cast, it becomes a 1, and then the next
spell adds 2 to SS, making it 3, so you have an 85% chance now, as
opposed to 0 +4 +2=6 SS or 70% chance of evasion/half damage/etc.

Well yes, but the RNG is a fickle mistress.

Effectively, yes.

Some spells apply a penalty to saving throws.

This thread is beginning to remind me of the time I tried to get a
girlfriend interested in playing AD&D. We were having a mock combat with a
cleric and a fighter against an enemy with AC 0...

Me: 'See, my THAC0 is 5. So I have to roll 5 or better on this 20-sided
dice.'
Her: 'My THAC0 is minus 1. I don't understand.'
Me: 'What?'
Her: 'Well, this dice only goes from 1 to 20. How do I roll minus 1?'

Maybe I should try again, now that 3rd Edition has tidied this up.

I am willing to be DM, but I got no players... I got lots of friends that
already knew AD&D2ed, but none of them are willing to spend time to play.
(Gee, they don't even play boardgames anymore!)

Do you have any advice for me?.... other than having a lot of girlfriends?
;P

Of course, we wouldn't want it anyother way. I think there is
anti-gamer conspiracy at Bioware. Saving throws are really made using
a die 4.
