Cut paste the following, into a newly created trigger.

PATTERN:
(%d)str (%d)int (%d)wis (%d)dex (%d)con

Action:
#IF (%1>20 & %2>14 & %3>16 & %4>15 & %5>21) {y} {N}

Explenation:
%1 = str, %2 = int, %3 = wis, %4 = dex %5 = con

Set the value for each % , 1 less that your aiming for, this enables you to accept that your willing to have lower wis/int(or any other stat) on a character as long as your other stats are allready maxed. Running stat rollers on total numbers is fine, but if you want to be more precise, I prefer this 1 liner. Simple fast and easy to understand & edit... no messy maths that needs to be worked out in your head



PS:

If you want to add in a charisma roll, add another (%d)cha on the pattern , then add a: & %6>15 , inside the round brackets.
