Need help to create a Macro that check success in 2d6 over 8 or more.

I want to make a macro that tells me if a roll of 2d6 adding a modifier and if the result is 8+ (depending of the difficulty level) the roll was successful, but if it is a natural 2 (1+1) it is automatically a failure. The level of success must be done 8+ if it is routine check, 10+ if it is difficult check, 12+ very difficult check and 14+ is a formidable check to be successful in the task.

Unfortunately roll20's success checking only works on a per-die basis. You can't check if multiple dice achieve a difficulty. The only way (without a Pro subscription) to do this would be to create a different rollable table for each difficulty, multpled by extra tables for each possible modifier (because Roll20's terrible implementation of rollable tables doesn't work with modifiers). That's not really a solution, sorry. The only manageable thing you can do is have the number printed out in chat, and then say whether it;s a success or failure. So you could print the target number with the roll. Here's a query that lets someone pick the difficulty and it'll print out the target. ?{Difficulty|Routine,8+|Difficult,10+|Very Difficult,12+|Formidable,14+}

That’s not the only way.  The macro system is very robust if you can think outside the box. I had the same problem with writing a morale check macro for my AD&D 2e game. The only difference here is it’s a 2d6 roll instead of a 2d10 roll for morale. It should look something like this: [[1d6>[[(8-1d6-?{Modifier?|+0}*1)*1]]]]

Can you break down that roll so we can use it for other purposes, how dows it work to get 2d6 > 8 ?

Gigs, you can do success/failure for multiple dice as one roll via: {2d6,0d1}>8 It will check the 2d6 as a complete roll rather than each d6 individually.  Luis, I suggest the following macro: (rename the names of things as desired) &{template:default} {{name=Test Attack}} {{Success?=[[1t[[[{[[[[2d6]]+?{modifier}]],0}>?{difficulty}]]SuccessFail]]]}} {{Roll with modifiers=$[[1]]}} {{Snake eyes check=$[[0]]}} Then make two Rollable tables.  First table name: "1SuccessFail" (without quotes) Second table name: "0SuccessFail" (without quotes) First table make a single entry: label it "Success" (without quotes) Second table make a single entry: label it "Failure" (without quotes) The above macro will make a success/failure check and display that. Then it will tell you the Roll with modifiers so you can determine the degree of success. Degrees of success cannot be automated with a rolled macro very easily, if at all.  Then it will tell you the Roll without modifiers so you can easily see if it was a 1+1. 

Thank you Gauss, I should have remembered the (2d6,0d1} method (especially since I've suggested it on the forums before, and the inverse, rolling under a target which adds a little complication). Good suggestion on the tables if needed.
