I have an unusual calculation for critical success with attacks in 3.5. The standard is, if your attack roll is 10 higher than the targets armor class you get a critical. With weapons that have a critical range this is reduced, so a sword with a normal critical range of 19-20 gets a critical at 9 higher than the armor class and so on. So, I tried to have it as attack roll cs> (weapon's critical range-10+target armor) but it doesn't seem to work. Actual macro is [[1d20+@{selected|weapon1stat}+@{selected|weapon1enh}+@{selected|weapon1focus}+@{selected|babmab}+@{selected|sizemodmab}
cs>[[@{selected|weapon1critmin}-10+@{target|bar2}]]]]
