 The leader Uruk will have a range of strengths and weaknesses , the latter that can be exploited in combat to quickly weaken and defeat the leader . The player can gain knowledge of these through finding intelligence mostly by draining and interrogating marked Uruks for this . Being able to exploit such weaknesses in defeating the leader will gain a better quality rune and more experience points in this manner . Once the player gains the ability to brand Uruks , they can brand these leaders and convert portions of Sauron 's army to their side . At this point , the player can use the Nemesis system to trigger infighting within the Uruk forces which they can then directly participate in , helping to weaken the army further . Uruks that survive their encounter with Talion will remember this when Talion combats them again ; for example , an Uruk who was thrown into a fire by Talion might want revenge on him for being disfigured .
