So I found some really great stuff on the manual but I think the roll mechanic I'm looking for is missing.
Is there an easy way to make this, or am I missing a detail?
What I'm looking for is a d% roll where you roll a skill modified by Attribute+Skill and have to roll under that target.

So in the example this is an archery attack roll. It should be Agility (30) + Archery (10) to give a DC of 40. Roll d% to be under 40.
Unfortunately when I use /rollunder 1d100x(p1)+(a)-1 it is adding reference number a (the agility score) as automatic successes, in this case adding 30 to the success roll.
For anyone else curious about this, the -1 just removes one success because moreCore rolls a d100+d10 to get a d% result and the system counts the d10 roll as it's own thing. Meaning if your DC is 50 and you roll d% 70+5 (result 75) it will count as 1 success because the 5 is under 50.
