Again about the infected sore, i was thinking like change the chance to increase/decrease it's value based on the relation of CON/WILL. So, if someone has a lot more CON than WILL it would it more probably to increase than to decrease. Since new players has their stats more close to a balance it would not hurt they too much ( even more if the starting value decreases the chance of increasing ( uh?) ).
Something like: CON/(CON+WILL) - 10% chance to INCREASE the damage
WILL/(CON+WILL) + 10% chance to DECREASE the damage
Someone with 10 CON e 10 WILL = 10/20 - 10% = 40% chance to INCREASE the damage | 10/20 + 10% = 60% chance to DECREASE the damage;
Someone with 700 CON e 30 WILL = 700/730 - 10% = 85,8% chance to INCREASE the damage | 30/730 + 10%= 14,1% chance to DECREASE the damage;
Maybe you can still do it, and just make the soap increase even more the base chance to decrease the damage
