I am simply posting here since it is even more relevant to PvP since it will disable Lightning Rod all game.
When Lightning Rod procs from the fear of Nightmare Rune, Lightning Rod simply stops working until the player respecs it.
In the video, I use Gust as a proof that I have Lightning Rod. After that, I ask the thief to strike me until he gets Feared by Nightmare Runes. The Lightning Rod procs twice (strange behavior). Then, I use Static Field, stun the thief and Lightning Rod does not proc anymore. This glitch remains all game and from anything that CC, not just Static Field.
