Using d100/d%'s

I like that I can tell new players 'your skill is your % chance of succeeding under most circumstances'

It's much easier for them to contextualize than 'your skill is an abstract value that you add to a d20 roll in hopes of hitting an arbitrary target number'

For real though d100 has been done to death and you should definitely read the existing rulesets before making your own

Most people would prefer two d10's rather than one of those golf balls though.

From what I recall of Call of Cthulhu, d100s were used for skills. So basically if your driving skill was 50, rolling under a 50 would be a success. As you level your skill increases, so eventually your driving skill could be 60 and you're now more likely to succeed.

I will make a d% system that works with one roll (assuming XY, where X is tens and Y is singles):

XY is your hit chance;
YX is hit location;
X+Y do something;
| X-Y | do something;
X * Y do something;

Still thinking on the somethings.

Elaborate, please. How do each of these work, perhaps with a small example per case if you would.

Hmm, so I looked it up on anydice
XY and YX are just your normal d100 distributions, just flipped (90 hit would be 09 location)
X+Y are triangular distribution, between 2 and 20 with mean 11
|X-Y| has a weird graph with it starting at 0 with 10%, going up to 1 with 18% and each further probability being the previous -2% (so 16%, 14%, 12%, etc.)
X*Y is just gibberish, with it going from 1 to 100, skipping the prime numbers larger than ten and probabilities swinging between 1% and 4%

Pic related are the graphs, note that you can only see YX due to it being identical to XY

Is this thread trying to say you have to use those goofy balls instead of 2 D10s.????

2 D10s is literally a D100. You don't need that goofy thing. I just need someone to confirm that this thread isn't being stupid.

At that CoC is a "percent" system.

So I can teleport randomly on a map while hitting?

And doing 3 other things that requires really wierd numbers and a very high problem in terms of balance?

What's the point? Why not just say I go here and toss the 3 pointless numbers to make it easy?

what

>>54088153
well, overall efficiency could be one thing, where you get your hit, hit location, damage, and possible bonus effect from a single roll simply by reading it in different ways

>>54087956
2 d10 is peasant madness, and any die besides d6 looks retarded.

>>54088204
I thought he meant map location not hit location. My fault. At that making it only a die roll takes away a large chunk of RP. I'd honestly rather have it like pathfinder where you get a -5 on a specific body part but otherwise you can just describe where you hit and how hard based on Dmg and desire/RP.

>>54088404
So everyone would have the exact same damage meaning no diversity between characters damage? Unless you made type of dmg a thing like slashing VS blunt or Elemental or something. Otherwise we are all just making the whole game a dice roll fest and taking away the RP and Min Max of it.

I did once use a unusual crit system that used a D30 with a list of different Critical outcomes. One being cut off and arm, another being make Target a retard. But I personally didn't like that style.

Palladium games like Rifts use d100 for skills checks and I think it's the best way to go about it. If you want some inspiration check out the skills section of the Rifts Game Master guide there's some good information there that could help give some ideas. I think there could be some issues with combat. Perhaps you could do an array of combat maneuvers like %chance to hit with weapon X and a %chance to parry with weapon Y.
