Percentage Rolls

[Deleon]

When you make a percentage roll, are you trying to roll higher or lower than the given percentage? For example, if your target has concealment, and there is a 20% chance that you will miss him with a successful attack roll, are you trying to roll higher or lower than 20 with the percentage dice?

Huh? *blinks*

If something has a 20% of happening (like the miss chance here), roll d%; if the result is 20 or less, the chance (here: the miss) came true.

Of course, no one hinders you to take your 20% onto whatever yields the same results, like 1-4 on d20, 17-20 on d20, or whatever.

If you roll lower than or equal to the stated percentage, the effect happens. For example, if you have a 20% miss chance, a roll of 01 to 20 misses or 21 to 00 may hit. The GM might allow a different die roll that has an equivalent chance of success (such as missing on 1 to 4 on d20).

The general assumption is "higher is always better" (for the dice roller) unless the roller states otherwise before the roll.

OK, got it, thank you. :)

Not sure why you necro'ed this thread for that question, and not sure if I understand it, but here is an attempt to make a suitable answer:

On d% or d100 rolls, you typically use two ten siders, one marked 0-9 and the other marked 00-90 by tens.

If you roll both the 0 on the "ones" die, and 00 on the "tens" die, that is read as 100.

0 & 00 = 100
1 & 00 = 01
0 & 10 = 10
5 & 20 = 25
9 & 90 = 99
Etc.
