Each player rolls a different weighted 12-sided die depending on the number of troops the player has (see table). The attacker wins on a tie.

1-5 armies 6-10 armies 11-18 armies 19-30 armies 30+ armies

The number of troop losses depends on the lowest ranked die thrown. Example: an orange die (rank 3) vs a yellow die (rank 2) results in 2 troop losses.

These rules give more advantage to larger armies (die scales to 30+ armies), and resolves large battles quickly.
