I already asked if this was in the game in this post -> <a href="https://app.roll20.net/forum/post/397333/subtracting-from-attributes/#post-397409" rel="nofollow">https://app.roll20.net/forum/post/397333/subtracting-from-attributes/#post-397409</a> but I was told it's not. If you make a new command (a pass by value instead of reference) that would allow you to edit the numbers and stats it would increase the quality of game play imo. John R. in my previous post noted this would also be helpful with ammo. So here is how it would go: --------------------------------------------- Attributes(Before Combat): Health 10/10 AC 17/17 Ammo 24/24 --------------------------------------------- Macros -> Add -> Name -"Fire Crossbow" /me fires his crossbow! /roll 1d20 (Made up attack value) /roll 1d4 (Made up damage value) Arrows Left: [[${Axel|Ammo} -1]] ($ is the made up command in order to change the variable) ----------------------------------------------- Output: Axel fires his crossbow! ---- (Attack Roll) (Damage Roll) Arrows Left: 23 ----------------------------------------------- Attributes(After Combat): Health 10/10 AC 17/17 Ammo 23/24 This method can have a lot of uses, like for keeping track of Ammo, Power Points, Temp increasing stats via rage boosts, etc. Being able to increase and decrease variables and attributes may sound lazy, but it will more than likely smooth out many parts of game play that would otherwise be used up fiddling with things. It's more of a want than a need, but I can say this would be a very good feature to have.
