I've reviewed many of the proposed methods, most I've tried, and most end up either being too hard, too complex, or too soft.
After taking a long look at the system, I find the problem may rest in the dice. The fact is we have several different ways to increase our success rate in the system (a reckless die, a conservative die, an expertise die, and a fortune die) while we only have two dice to represent challenge (misfortune die, and a challenge die). What I think may solve the problem would be the inclusion of a third difficulty die, for now lets call it a proficiency die which are added to a pool when a character is acting against someone with levels of skills (creatures would be able to spend some of their pools to get access to these dice as well).
Basically the rough idea would be one Proficiency die would be added to the pool for each rank of expertise the character has in a skill. So a character with two skill, would add two proficiency dice to the check of an opponent when they roll to hit them...the difficulty pool ending up as (1 purple, 2 Expertise + any other additional dice from an action card). If the die is properly designed, it would be like an super misfortune die, but not quite as brutal as a challenge die, almost like a mid-step. So far this was my basic layout for it. For now, the die would be a D6 (probably orange as to keep it being confused with the other dice) and the sides would look like this:
2 Fail sides
1 Fail & 1 Bane side.
1 Bane side.
I am not sure if it would need a fifth side, but based on these numbers, the die would have roughly a 50% fail rate, a 33% Bane rate with the including the powerful fail and a bane result (much like the hammer boon effect on the stance die).
I don't know, for sure if the other two sides should be blank, but I could see maybe one being a Chaos star or another fail and bane side or a fail and a chaos star, I'm just not sure as of yet.
So my question to you guys is what do you think of the idea? What do you think of the die sides and any suggestions on how to make it better? I was debating about putting it on a d10 instead and I am strongly considering it, any thoughts? How else could you see the die being used? One other way that quickly jumped out, is when you try to sneak past someone or spot someone sneaking, this special die would be placed on them based on skill ranks as well. It would also work well for magic resistance and counter magic.
Anyway, give me your thoughts.
(I have that thing in my head, that doesn't allow me to focus on anything until I at least partially deal with the problem, it's irritating like hell, especially when I can't find a satisfying solution).
