Defining a attribute?

Is it possible to modify a attribute on a character sheet using a string? Right now I have a spell that I roll 6 hit die: [[1d20+@{INT-mod}+@{level}+@{Escdie}]], [[1d20+@{INT-mod}+@{level}+@{Escdie}]], [[1d20+@{INT-mod}+@{level}+@{Escdie}]], [[1d20+@{INT-mod}+@{level}+@{Escdie}]], [[1d20+@{INT-mod}+@{level}+@{Escdie}]], [[1d20+@{INT-mod}+@{level}+@{Escdie}]] Is their a way to make the @{Escdie} into a ?@{Escdie} that will change the value in the attributes & abilities tab of my character sheet. This is for a 13th age game and the spell is Force Salvo. My game is using the 13th Age Official Sheet

I think only an API can do that. If the creator of your game is currently a Pro subscriber it should be theoretically possible, but I don't know much about APIs as I'm a free member.

Dakota is correct: the macros available to free and Plus users cannot make changes to a character sheet. They can only read values from sheets, not write to them.

so I found out if you create a custom Attribute on your character sheet, you can do a @{value}, and just change the value manually, however I also found out that if you do ?{value}, it does not ask every time you place it in the string, roll20 recognises that their the same and uses that 1 call for all of the same entries. So I just changed my string to be  [[1d20+@{INT-mod}+@{level}+?{Escdie}]], [[1d20+@{INT-mod}+@{level}+?{Escdie}]], [[1d20+@{INT-mod}+@{level}+?{Escdie}]], [[1d20+@{INT-mod}+@{level}+?{Escdie}]], [[1d20+@{INT-mod}+@{level}+?{Escdie}]], [[1d20+@{INT-mod}+@{level}+?{Escdie}]] Im still looking to if their is a way to just write the string once and have it repeat 1+@{INT-mod} times. but so far no luck.
