Thanks
My "feel" from my RL expereince with WMA, is  that unless one "fumbles" its not about passing a teast to do something, its about bout doing it better than your opponent. maybe with spreading ones skill amongst the options chosen. So if I choose to offline - parry - strike, I would have to spread my skill level across those three actions? If I only attempted 1 action I would roll the dice alloted to my skill stat, for each extra action I try in the same passage, I go down one die and roll one of that type of die for each action..

Going a bit OT from your original post.

Hello everyone..This is a new UPDATE..
important: i have read the posts about skills or traits, skill vs traits, yes skills no traits...so i know where im stepping on and therefore this is not a final solution..its just a thought

CONCERNING TRAITS AND SKILLS.

OPTION 1 - STATS GIVE BONUS TO TRAITS (with a twist )

i.e: If the elven archer has a nattural excellent (d20) dexterity he has a +3 in his skills that are dexterity based/related.(the d20 is 3 steps away from the d8.)
Let us consider that he has a fair archery training (d10). Now, take a look at the twist:
The twist: the +3 bonus apllies only if he suceeded in his roll. (rolling over 4).If he rolls a 2 he doesnt scores 5. But, if he rolls 5 he scores 8.

This option allows the felling of the (heavy gear rpg) where his skills are his chance os sucess and his good natural apptitude amplify his scores. The stats work as his degree of sucess.. That way two characters with the same traing will have different results. The more tallented one will also hit the target but will also hit better.

The contrary apllies. When having a stat under d8 you get a penalty for every step under it.

If a person has no training in a skill she rolls a d4. Plus or less the step difference from his traits.
i.e: a character with poor (d6) dexterity with no climb skills roll a d4 -1. This gives him a 18,75% chance of sucess. (is that right?)
i.e: a beserker.. he has an excellent strength (d20) and a poor dexterity..(d6). Let us say that he has no training with hammers and just picked up one from the floor.. He has a low chance of hitting anyone (18,75% if thats right) but he does a LOT of damage. If he rolls a 4 and then a 2 he scores 5 (6 -1dexterity). HOWEVER, theres a +3 bonus from his trength that increases his degree of sucess.. He scores 8, and a large hammer has a x4 multiplier..Any attempt to defend or dodge that scores under 5 (misses) and he will really hurt(8-4=4) his opponent with one blow.(4x4=16, hp is stax5, normally 25)

NOW, ON OPTION 2..I ALREADY HAVE IT WRITTEN BUT IM RUNNING OUT OF TIME.. ILL POST IT LATER..KEEP THE FEEDBACKS AND THANKS TO ALL..
BYE

Hi there!
I'm new at The Forge and I have some long ago written stuff here about dice. Hope it's good for something.

So.
When you throw a dice once, the probability for a given value to occure is the same for every value, i.e. 100/nr. sides.
This is ture for every die, no matter how many sides does it have.
However, if you roll it more then one times, the bell-shape starts to appear. More on this later.

Another important parameter is the average.
Here are some values:
die  average
2D4: 5
3D4: 7.5
2D6: 7
3D6 10.5

One can see, that the average for xDy is x*(1+y) / 2. Simple isn't it?

Some other frequent die setting I've met with:
1D6+14: 17.5
1D6+12: 15.5
1D10+10: 15.5
1D10+8(2x): 15.15
2D6+6(2x): 14.36
1D10+8: 13.5
2D6+6: 13
3D6(2x): 12.17
1D10+6: 11.5
3D6: 10.5
1D6+5: 8.5
1D6+4: 7.5
1D6+3: 6.5
1D6+2: 5.5
1D6+1: 4.5


And now about those bell-shapes. Why do they occure? It's because when you throw more than one times with a die (and add the results), a higher sum has more ways to be the result, then a smaller one. For example with 3D6 you can have the sum of 11 from the following die-settings: 1-1-9, 1-2-8, 1-3-7, 1-4-6, 1-5-5, 1-6-4, 1-7-3, 1-8-2, 1-9-1, 2-1-8, 2-2-7, 2-3-6, 2-4-5, 2-5-4, 2-6-3, 2-7-2...and lots and lots more. On the other hand the sum of 3 can appear only if you throw 3 times 1. Slim is the chanse, is it not?

Some numbers:

If anybody needs these values for some other die-settings, or any other things like these, post your question, and I'l post back as soon as I can.
Hope it helps.

Appologies for spelling (and other) errors, english isn't my first language.

Thanks for the info..Quite a handfull to have all the probabilities already calculated.

Im still sticking with my previous mechanic, but im developing a new one that will require much of your info..

Thanks again..

NEW UPDATE !!!

Hello again.. This is my update on skills..how you buy them and so on..check it out..

Lets say that the GM gives you a certain number of dices to buy your skills..*
*(im still thinking about, but probably 50 points, or 1 d4, 1d6, 1d8, 1d10, 1d12 and more 2d10 (1d20))

The skills are freeform..you choose what you want.. doesnt matter its focus (that will depend on the style and GM)
The twist: when i choose a skil i may use everything related to it with that dice or give higher/lower values but keeping the balance. And i can only increase something one step higher.
i.e: i choose as a swashbuckler to buy fair fencing (d10). i can use all things related to fencing with a d10 OR,

i come up with a special disarm manuever..and give it a d12, im great doing it.. i dont have to use my d12..i just increase my speciall manuever because now i must balance it..therefore i must get 2d6 or 1d8 and 1d4 in two other things..

ie: i used one d10 and bought fencing. I decided that i have a speciall disarm manuever with a d12. That extra training in this manuever got me a bad charge manuever (d4) and poor training in lets say..ettiquette. I trained much and knowing i can disarm my opponents made me arrogant..

I know that post isn well written..i may post it back again.. the main point is..buy a skill..(using one of your dices..) you may lower or increase some specialities under it but only if you keep the dices at balance..

I hope that you like (at least those who understand it..sorry guys) and please send in your opnions.

bye,
mauricio
