Is it possible to increment or decriment an Attribute from a macro

I am working with a custom system. I have an ability that when the player uses it it needs to increment one of their attributes. Something along the lines of Draw Steel's heroic resource. When they perform an ability, they they increment their resource. I can have the player manually increment it, but they often forget.

You can do this if you make extensive use of Custom Roll Parsing, or use a script. This is the sort of thing that used to be impossible before Custom Roll Parsing.

Hi TysonNW,  You cannot make changes to an Attribute using a Macro without some 'extra help' from a Mod (API Script).  If your game owner has a Pro account then a script like ChatSetAttr can do the job.  Alternately, a Character Sheet can be built to do that without needing a Mod. That is what GiGs was referencing with the Custom Roll Parsing.
