How are you supposed to do combined strength checks? Under the rule of Aid Another, it only talks about combining skill checks. Am I supposed to use the same DC 10, add +2 for Strength too, or would players combine all their strength checks for a total?
I have always allowed for aid another on skill checks but I think per RAW it only works on skill checks, attack rolls, and boosting AC, and some spells(Don't ask me which ones, I am going by what the book says.) :)
