Math in Macro Names

My friends and I are playing Pokémon Tabletop United, a system where damage is broken up into 28 distinct hit dice sets called Damage Bases, or DB for short. To give you a frame of reference, db4 is equivalent to 1d8+5, whereas db6 is equivalent to 2d6+8, and the hit dice get larger as you go up. I've incorporated all 28 damage bases as macros in my game, but like in many other RPGs, I would like to be able to provide modifiers to damage base totals. For example, the move Tackle (also a macro since it is a very common move) has a Damage Base of 4, and I want to provide a bonus that increases its damage base to 6. Tackle runs #db4 as a macro, so I thought that something along the lines of #db[[4+Bonus]] would work so that I could change the called macro to a higher value. Does anyone know how to make these modifications?

You could put query ( ?{Modifier|0} ) in the macro. Example: 1d8+5 +?{Modifier|0} The format for a query is ?{Query name|Default Value} Alternately, if you type #db4 into the chat log you can manually add something to the end of it and it will be added to the last line of the macro. Example: #db4 +5 will add +5 to the last line of the macro.

That's what I've settled for as of now. But here's what I'd like to do: Say for example that there is a bonus that temporarily increases Damage Base by 2. I would like to be able to apply some kind of modification to the #db4 macro (which rolls 1d8+5) that increases it by 2 to the #db6 macro (which rolls 2d6+8) Does this make sense?

perhaps you could do something with calculated die rolls? Syntax: (N+Y)dX or Nd(X+Y) Example: 1d( 6 + @?{Sides Bonus|0} ) (I haven't tested this yet, but I believe that should default to 1d6, but ask you if you want to add a bonus to the 6. If you were to enter a 2 that would become 1d8.)

Yeah, but if you look closely, db6 and db4 don't even roll the same kinds of dice. My intention is to mathematically change the name of a macro in order to call a different kind of die roll. I understand that this is unusual, sorry.

Being a mentor you have access to the API. Using the API you can create a custom function that can be called from chat that will take in the current damage base and a modifier and then make the appropriate roll. Here is a link to a topic in the script forum that can show you how to create and call a custom function. What you need to do is a lot less complicated than what they have done. I can probably help get you reasonably close to the script you need, but only if you want to go that route.

I definitely saw a few things in there that look like they'll help, but this API stuff is still pretty much Greek to me...
