Defeating Orc Veterans
In the Minas Tirith and Pelennor Fields levels, your basic Orc Veteran has at least 20,000 HP. You can use Berethor's Orc Bane twice to kill them. If it does not die, just use a plain attack to save your AP.
In Osgilath, you will encounter the big Orc featured in Lord Of The Rings: The Return Of The King. First, use Farimir's Quality (where he will counter attack for someone). Do it to everybody. He will counter attack for everyone with a volley of arrows. Then, use Captain's Volley until he runs away. For Berethor, use Ecthelion Wrath. For Idrial, use Loud Water Fury. For Eadon, use Rupture Armor. You may also want to use Morgul Decay. Do not have Elgost out, as he misses to much. It is best to have Idrial, Eadon, Berothor, or Morwen.
