'Nay, take this evil thing..I can bear it no longer! My apologies, friend, but the sense of this thing is too much likened to the terror of Rammas Deluon. I cannot bear its presence.
'But I know now the secret of the stones of Rammas Deluon. It is no spell that grants the statues such power, but a fell spirit of an elder Age, such as those that inhabit the wights which serve Angmar. This stone-heart was prepared to receive such a spirit.
'Perhaps this heart may be made to draw forth such a spirit from another stone. It may be a clue to breaking the will of the watching-stones! Take this stone-heart to the ancient watching-stone which stands near the eastern pass of Ram Dúath to the east of here, not far from Bail Róva, a fortress of the Angmarim'
Corunir reacted strangely to the presence and touch of the stone-heart, recoiling from it in terror. He told you that the heart had been prepared to receive a fell spirit from an elder Age, similar to those that inhabit the wights which serve Angmar.
Defeat the spirit of the ancient watching-stone
The ancient watching-stone is near the eastern pass of Ram Dúath, near Bail Róva, east of Aughaire.
Corunir believes that the stone-heart may be able to draw forth the fell spirit from another watching-stone and has asked you to test his theory upon an ancient watching-stone which guards the passes of Ram Dúath.
Talk to Corunir
Corunir is at the Hillman-village of Aughaire, west of Bail Róva.
With the spirit of the ancient watching-stone defeated, you should return to COrunir with the news of hope.
Conqueror of the Watching-stones
You can shrug off the worst effects of the Fell Watching-stones' oppressive will.
Recieving this Characteristic allows you entry into the Eastern portion of Angmar past the watching stones. If you do not have this characteristic you will die upon getting close to them.
The Enraged Fell-spirit can be found in Ram Duath, at [1.1S 35.5W] or [3.9S 36.0W]. Click on the weatching-stone to present the heart stone. This will draw him out. He is a ranged mob so if you can fall back you can make this a ranged encounter. This also helps by backing you out of the worst of the Dread effect from the Watching-stone.
