Hello there. I've been trying to get a handle on Aaron's Token Mod API in a Macro. I'm running a homebrew in 5e which has the existing AC rolled with a D20 and subtracted by 10. Using the API I'm wanting to have a roll with attribute reference the sheet's @{ac} then set a new Attribute called Armor_Class. Below is the code after I tweaked it some, but it isn't setting the Armor_Class value. !token-mod --set Armor_Class|[[1d20+@{ac}-10]] I have tried the inline roll with quotes, with the @{ac} as @{Selected|ac} I want it to set a new attribute so the players can put their AC in as normal and I can call the Armor_Class as a whisper to lessen their confusion and prevent me from asking "What's your AC this round". I feel like I'm missing something rather simple here. Thank you for reading and responding.
