I know I have done Everything, the problem wasn't it was hard, because it isnt. problem was, And ive seen many have it, that one orc, once a caster too, become invulnerable and just runs around. Another problem was, friendly npcs turning hostile, like the cat, and Mayor of the Town, without you attacking them. Like depending on wether they already aggroed the orcs Before etc. When they aggroed orc first, they stayed friendly, but got killed by the humans AOE and Rickochet etc. But killing all orcs vefore the fight solved this, this however is not what you should have to do to get by.
