In Middle-Earth: Shadow of Mordor, acquiring a Level-25 Rune can be a hard process, especially if you don’t know what you need to do.
There are some players who confuse a Level-25 Rune with Epic Runes, but both of these things are quite different from each other. Follow the steps below and you will acquire Level-25 Rune:
First off, you need to die by the Uruk you need to acquire a Level-25 Rune from. The idea is to keep on dying by the same Uruk over and over again until that particular Uruk is Level 20.
It is a good idea to find an already high-level Uruk and then get it to Level 20. I would recommend searching the areas in the Sea of Nurn because this portion of map contains many high-level Uruks.
Tip: Never send a Death Threat to an Uruk or it will drop an Epic Rune.
This step is extremely important! You need to find the Worms and acquire Intel on that particular Level 20 Uruk. Keep on gathering Intel until you know all about its weaknesses and strengths.
Another thing that you need to make sure is that particular Uruk should have a Fear or Hate. Once you have completed the above steps, kill its Warchief and all its bodyguards instead of the Level 20 Uruk.
Once you have done that, the Level 20 Uruk will be promoted to the rank of the Warchief. The last thing that you need to do is to trigger the Warchief’s Fear or Hate followed by killing the Warchief and getting the Level 25 Rune.
