Hello, this stop fight, but bot probably try to attack again target, to skip all combat you need to use code like:
wManager.Events.FightEvents.OnFightStart += delegate(WoWUnit unit, CancelEventArgs cancelable)
{
cancelable.Cancel = true;
if (unit.IsValid)
ObjectManager.BlackListGetUnitAttackPlayerGuidTime.Add(unit.Guid, DateTime.Now + TimeSpan.FromMinutes(10));
};
