Hey guys, really quick question, and I want to get a consensus,

My friends and I were playing today and we had a life or death situation with a daemon.

I rolled a 0 (on the tens die, representing 00) and a 0 (ones die), and we were debating on whether I rolled a 100 (00 and 0, in my view, is 100, since you cant get 0 on a roll), but one of the other guys in my group said that it is 10 (00 on the tens is 0 plus 0 on the tens is 10, total 10). My DM eventually ordered me to reroll because the debate lasted too long.

We ended up killing the deamon anyway.

What do you guys think? Is rolling a 00 and a 0 equal 100, or 10?

Well,

since it is called a "D100" it would be kind of foolish if there wasn't a chance to actually roll a 100.

Apart from that there would be two instances to get a "10" result which would unbalance the total randomness somewhat, too.

So indeed, double 0 (00) is counted as "100"

Okay, ya, there is NO WAY 00 0 is a 10. As pointed out, a 10 is already possible (10+0) thus it can't come up twice on a d100. As for what 00 0 is, I've always understood it to be 100 and in 20 some odd years of playing, that's how it's been interpreted in every group I've played with. I've had a couple of new players now and again think it was 0, but if that were so, then it would be a d99 and not a d100.

Finally, if you need something in the core book to make the decision final, look on page 9 in the blackish box. It states: "The most common use of dice is the percentage roll (abbreviated to d% or d100). This roll produces a number between 1 and 100." As stated by the RAW, an unmodified roll of 0 is impossible, and there can't be a higher probability of getting one number above anouther whi9ch would moslty invalidate d100 as a proper random number mechanic, so it must mean 100 ;-)

Since "0" on the last digit of the D100 is always a zero instead of a ten... yep, it's a 100.

That kinda sucked when while dodging a bolt round I rolled first the die for the tens and it came up 00 and I went "Yay!" and then the stupid ones die came up 0 too...

Hey thanks guys.

Im glad that I got that fixed.

Well, as a DM, I rolled a 100 in a strength contest against one of my players. What was the NPC? Why, the demon that appear in the adventure of the Dark Heresy Basic Book.

Kinai.

Just a quick aside... in our game yesterday, our GM rolled a 100, our Psyker rolled two 100s and our Guardsman rolled two 100s in one session. Five 100s in one game. Go figure...

We had one guy in our group insist that was the only logical way to read a d100. In fact, he still does and complain about it every time he's 'forced' to submit to our nonsense way of reading the dice.

00 + 0 = 10.

90 + 0 = 100.

The rest of us just look at him like he's crazy. How can you live for 30 years and never roll a d100 before?

Me and a friend began rollplaying without access to any rulebooks and all we figuered the only logical way was the 90+10, but it doesnt matter how you role your dice, you just have to do it the same way everytime.

Slaunyeh said:

If thats true, you have to do that with every 10s column, otherwise you have two ways of rolling a 10, and no ways of rolling a 90

2x 1D10 can roll as either 0-99 or 1-100

Every single percentile system I know is 1-100 based so on a roll of 00 it actually =100 (yes it's a fudge but it works and is second nature)

Thing I find difficult is ensuring you remember which dice is the tens dice!

And statistically 100 does come up randomly 1 time in 100 rolls.

Did anyone see a test that was made of the true d100? It showed the dice was 20-80 heavy in it's rolls.

There are D10 where the numbers read 00 to 90.

Are you talking about a specific d100 or the d100 in general?

This system works and makes sense as long as you always treat 0 as +10, but the other system is much easier as you don't need to add anything.

Slaunyeh said:

Tell him the dice that counts by tens is actually the tens "digit". They put the zeros there so you can remember it easier.

I've only seen 2 games in my 32 years of gaming where 00 was read as 0... and Dark Heresy is not one of them.

00 is 100. Your GM isn't the sharpest tool in the shed. The rest of the group make him look sharp, at least on this score.

Page 6: "The most common use of dice is the percentage roll (abbreviated to d% or d100). This roll produces a number between 1 and 100."

0 is not between 1 and 100.

You botched, and should have paid the price. A reroll was a nicety.

you can solve this pretty quickly by comparing a D100 in EVERY SINGLE game that uses such a die. 00 0 HAS ALWAYS been 100, whereas 00 1 is '1' and 10 0 is '10'

Not every game. I've seen two that count 00 as 0. (out of many dozens.) Just almost every game.
