Hi all, This quest could be very hard with a bad team, or could be easy with a very strong team.

I was a level 41 champion when i did this quest, It was very easy, you just need this in the group:

2 Ministrels (One for the full group and the other for personal healing to the Tank)
1 or 2 Hunters level 50 (For Heart Seeker and high damage and DOT)
Champion from level 45-50 (For extreme Damage per Second and tank if you do not get a Guardian)

If you could not get the second Hunter ask for another Champion or for a Capitan for some buffs and pets.

And yourself, no matter what class are you, if you are a Champion deal damage, if you are a Ministrel heal, if you are a Hunter deal high damage, If you are Burglar use your bag of tricks, If you are Guardian just stay there and recive damage, and if you are Lore Master just keep stuning adds and dealing damage to the Nazgul.

Hope I help, Good luck with it!
