Victor P. said: Hi, I'm on my journey to understand and master macros, and got a doub about something I'm trying to achieve. When I have a macro with a input value prompt, the var can be passed from the chat with #d20 4. If I have an Ability, can I pass a variable within the %{selected|Ability1} call? How? Hey, Victor P. ! That's a very commendable journey! Frequently-changing variables within Abilities are usually set up as Roll Queries (and sometimes as Attributes , especially when paired with the API Pro feature , which can modify Attribute values).
