Sorry about the delay, but I've not seen the author of the rules for 3 weeks or so. Ghazis are impetuous. If left to themselves, they will move towards the nearest enemy.
Battles continue until one army has fled the field.
Armies that have lost 12 points worth of elements decome demoralised. Loss of the commander counts as 6 army points lost. Once demoralised, elements flee unless halted. Commanders roll 1D6 for number of units or groups that they may move. The dice score is modified by the commander's ability.
