D&D 5th Edition: Elemental Adept Macro

So I was wanting to make a Sorcerer character, just an all out fire blaster. I really like the Elemental Adept feat, it gives two very good benefits. Page 166, PHB "Elemental Adept Prerequisite: The ability to cast at least one spell When you gain this feat, choose one of the following damage types: acid, cold, fire, lightning, or thunder. Spells you cast ignore resistance to damage of the chosen type. In addition, when you roll damage for a spell you cast that deals damage of that type, you can treat any 1 on a damage die as a 2 . You can select this feat multiple times. Each time you do so, you must choose a different damage type." So, ignore resistance is easy... but if I wanted to make a macro for this on my fire spells, what would I do to change all 1's rolled into 2's?

[[ { 2 , 1d8 }KH1 ]] If you ended up rolling a 1 on that 1d8, it would see "2" as higher and keep that.

I'm not sure, but I think there are far too many spaces between the brackets. Regardless of how I format it, every time I try and post the macro I get this error: "Cannot mix M and sum rolls in a roll group". Edit: Is it exactly copy/pasted from [[ { 2 , 1d8 }KH1 ]] ? Or is there a different way to do this?

I couldn't get the exact command you said, but with a small tweak I got it to work. [[ { 2d1 , 1d8 }KH1 ]]
