Yeah . Too bad we ' ll never see them again , though . <| sep |> For the math , if you use electronic aids on the table , there are countless apps and websites for dice rolling that can also do additionsubstraction etc . Another thing you might want to look into , is Roll 20 . Maybe not to use it as a medium for your group to play on , but to help you out . Pretty much everything can be programmed in it for rolling attacks etc . In that case , only the obscure moves would be a challenge . If you really just want to have fun with friends , be honest about it . Tell them that at times you will need a little help . As a DM there is already so much to do , that some help from players is always nice . Given the obscure moves you refer to , I do suggest reading the statblock an extra time before play , so you have some idea on how it works . The moment you want to use one of those moves , just be like Hey Joe , I have this move that I want to use , but could you do a check on how it works , just in case ? . Any group knowing about your autism will help you out . In the end , its about having fun together , as a group , not as individual players .
