Arrow proof, immunity to execution and frost are the <b>must</b> haves. Fire proof is nice, too, as the fire panic animation gives a lot of time to attack an Uruk. Soft-headed and fear of pinning instantly make an orc useless - most fears, really.<br><br>By the way, farming silver chests is MUCH faster than cycling through pit fight orcs, especially when you're at level 60. Save enough mirian for about 50 silver chests (not hard if you play online conquests), then open them all, recycling the orcs that aren't near perfect. You'll end up keeping maybe 10% of the orcs. Break down all the gear that you get from destroying those orcs and you'll have enough money for another good set of chests. Keep cycling through until you have a good set of orcs. MUCH faster than pit fight orcs.
