Any Captain or Warchief will drop a rune equal to their level (ex: Power Level 20 = Level 20 Rune). Then, if you meet certain conditions, you get bonus levels:
+1 Knowing weakness
+1 Exploiting fear
+1 Vengeance (Captain has killed you before)
+1 Death Threat
+2 Warchief

Don do death threat, it give epic rune.

find a captain that have easy fear like fire. Let it kill u, help him lvl 20 and send ur warchief to challenge him. In challenge, kill ur own warchief by press k and he will promote to warchief. Than u can exploit the warchief fear and kill him.
