however due to how the system handles fractional dice there is a solution that you can use. since your macro is a value divided by 3 and you want to always round down you'll just add into it after the division "-0.66" fractional dice are always rounded up so if you want to round down you have to subtract out the largest fractional for any given number. So if your equation would have normally given you a result of 3d6 it would instead now give 2.33d6 which will roll as 3d6 still, and likewise if the result was normally 3.66d6 it would have rolled 4d6 but will now result as 3d6
