Not sure if this is like dicey, but you can specify how many dice you’re rolling and it’ll send a message to you and to the other guy if you has his email.
It’s not very precise as it won’t divide up the different categories of attack dice, but for example:
Let’s say you’re attacking with 12 infantry, 4 artillery, and 3 tanks.
You would have the dice server roll 19 dice of 6 sides.
You would interpret the results as the first 8 rolls are infantry (ones), next 8 rolls are art/infantry (twos), and the last 3 are tanks (threes).
