Liberating caragors is by far more tedious than liberating slaves. To liberate caragors you have to break their cages. To liberate slaves you have to defeat or scare away their handlers. In the video below I show a method to get
four caragors a minute using the stronghold near the Fern Outskirts.
First, fast travel to the outskirts. Look right and jump down. In the ruins before oyu cross the bridge you can liberate 1 to 5 slaves by simply brutalising a guard. With the right skill set the second guard will flee and thus automatically reward you with some liberations. To brutalise a guard, walk up to him but before you get to him, hold
and push
. Even if the guard is alerted, this will brutalise him sending his colleague scattering away.
Now run across the bridge using the crates to trigger your Elven Swiftness. Climb up onto the bars and liberate three caragors. Notice how you can shoot through some of the other objects. As long as the prompt (
) shows in the bottom right hand corner. Notice how I shoot through the fourth cage which is located a bit further north of the other three cages. If you do it stealthily, you can fast travel immediately upon liberating the fourth caragor.
You can repeat this route once every minute and twenty seconds depending on the loading speed and your prowess. You will get all caragors done in thirteen repetitions leaving you with a good quarter hour which will also net you about fifty slaves liberated.
Slaves are rather easy to find. Look at your mini map and focus on the white triangles. I would suggest mounting a caragor. It is easier if you equip runes that grant Focus and Elf-Shot with the bow. Ideally also a rune that lets more than a few Uruks scatter when a nearby Uruk receives a head shot. I would recommend not bothering to actually melee any slave tenders unless it is only one. Sneak up on that one with the caragor with
and kill him quickly using
. If there are more Uruks, just kill them with your bow from afar.
Using these methods you should be done in about half an hour.
