Orthog Pain-Lover has been giving me a lot of trouble. He and his goons of spear-throwing hunters killed me a couple times, and it seems he's managed to get every resistance. I can't damage him with:
He's not immune to monsters, but I've seen him 1-hit caragors (that's part of how he got so powerful; multiple Beast Hunt events), so I don't feel great about that approach.
How do I kill Orthog?
To make sure that they stay dead, you need to behead them.
At least that's what the IGN Wiki tells me:
Death in the Nemesis System
Death is not the end in the Nemesis System: Not for Talion, and not always for the Uruks either. Whenever you kill a Captain or Warchief in Sauron's Army, there is a chance that they will survive the apparent killing blow. This can only happen if the Uruk in question was not beheaded in the finishing blow. Any Uruks that are lying down dead in the army page may come back and hunt Talion for revenge. After encountering them in the wild, they will reappear in the army page, now on their feet and sporting new scars based on their previous encounter. Some Uruks may even gain Strengths and Weaknesses depending on what happened to them.
Do they look like this?
If I'm not mistaken, those things are runes.
Whenever you kill a nemesis, there is a chance that they drop a rune. You can upgrade your weapons with these runes.
Best Answer
If an enemy is feared, their strengths will be lessened or negated.
In the case of Orthog, blowing up two nearby campfires when a feast event came up panicked him, and I could damage him with melee attacks in that state.
