Help making a more efficient macro

Hey there!  I'm not the best at macroing things in R20 and I'm trying to find a way to setup some stuff for skill use. What I'm hoping is that the following would be true: Attribute Result 0 0 1 2 2 4 3 7 4 10 5 14 It doesn't need to be a formula that works for any other attributes, but I'm hoping to find something that if the attribute is on the left, that the macro spits out the right.  I don't know how to do this efficiently.  Any help appreciated.

Hi Gary M, This should work for you: [[{@{charactername|attribute name },@{ charactername| attribute name }-1}>1*2 + {@{ charactername| attribute name },@{ charactername| attribute name }-1}>3*3 + {@{ charactername| attribute name },0}>5*4]] Please replace @{ charactername| attribute name } with the charactername and attribute name.  How it works:  {@{charactername|attribute name },@{ charactername| attribute name }-1}>1*2 This part checks for a "1" and a "2" (2-1) and compares that to a target number of 1. Each success is multiplied by 2. So if the attribute is a 1 = 1*2 = 2 and if the attribute is a 2 = 2*2 = 4 {@{ charactername| attribute name },@{ charactername| attribute name }-1}>3*3 This part checks for a "3" and a "4" (4-1) and compares that to the target number of 3. Each success is multiplied by 3.  So if the attribute is a 3 = 1*3 = 3 and if the attribute is a 4 = 2*3 = 6 {@{ charactername| attribute name },0}>5*4 This part checks for a "5" and compares that to the target number of 5. Each success is multiplied by 4.  So if the attribute is a 5 = 1*5 = 5 Then all the results are summed. 

Mathematically, a formula that generates that is: N*2 + Max(N-2,0) + Max(N-4,0) Translating that to a macro is harder.   Can you just use a Rollable table with the values 0,2,4,7,10,14 ?

Similar to Gauss': [[{[[0@{selected|attribute}]],0}>1*(2) + {[[0@{selected|attribute}]],0}>2*(2) + {[[0@{selected|attribute}]],0}>3*(3) + {[[0@{selected|attribute}]],0}>4*(3) + {[[0@{selected|attribute}]],0}>5*(4)}]]

As you can see, there a lot of ways of doing this but none of them are straightfotrward. This is the one I'd use /r {1,1,2,2,3,3,3,4,4,4,5,5,5,5}<@{attribute} or for inline roll syntax [[{1,1,2,2,3,3,3,4,4,4,5,5,5,5}<@{attribute}]] which you could use in a roll template. This compares @{attribute} against the numbers shown, and counts how many are equal to or under that total. If you repeat any numbers, it is counted again for each repeat. You might need to use @{ charactername| attribute } or @{selected | attribute } if using it in a macro (as opposed to a character ability).

The Aaron said: Mathematically, a formula that generates that is: N*2 + Max(N-2,0) + Max(N-4,0) Translating that to a macro is harder. This is the Keep High method, which would be /r @{ability} *2 + { @{ability}-2, 0 }kh1 + { @{ability}-4, 0 }kh1
