This works for both hunters and Minstrels and it doesn’t require potions, just skills
Simply start attacking from range, let the Gorthorog to get closer and when you are at 75% morale use fear (bards arrow or cry of the valar) to fear it. Let it get some ranged space and repeat. You should take him down in 3+ fear attempts.
Try to do it this way (fearing when loosing 25% of morale) since fear may be resisted so you will have to take some punches 
Also, for hunters, try this where the mob has no other mobs around that can be aggroed when in fear
This is a matter of choice and gameplay. In general Light Armor sets focus on will, fate and other non-DPS stats that help with a more passive (but active skill using) setup. Inthe other hand Medium Armor has more balance torwards agility for a more DPS type build.
If you like to solo a lot and you are a War Speech addict medium armor may be the choice for you.
If you prefer to focus on healing, groups and fellowships, be able to keep power and do some massive healings light may be the choice for you
You can always mix pieces depending on the stats you prefer.
lately a lot of buzz about Beleriand Damage Bows have been around. The truth is that when you reach level 50 and you are into Raids and Instances you will need to check (or ask a friendly Lore master) damage types.
A great example is Cudur (Ettenmoors Bow) one of the best bows around. Great for soloing but useless in places like Sarnur Instance where Westernesse and Light Damage will outperform Beleriand Damage weapons.
Lots of Lvl 50 weapons have light damage and that is good but for certain mobs (ask a friend Lore-Master) specially in the rep dungeons you will need Westernesse and Ancient Dwarf Make damage to get the most from your weapons. Those three damage types are the most common. Light will work on both situations.
2 Guardians, 1 Lore-Master, 1 Minstrel, 2 Hunters
Group will handle aggro (GRD), Hunters can take on the tanked mobs while Lore-Master handles adds and Minstrel Heals
Champions, Minstrel, Lore-Master and Burglar can make a kick ass fellowship. You will have multiple mobs DPS (CHM), Debuffs (LRM + BRG) and Healing + Power (MNS+LRM).
Eat food if you know you are going to have a big fight or if you are going to solo multiple mobs (if yo know you can) since DPS are low for this class and the fight will be long so the chance to loose power is 100%.
- Stay away from Barz when he says “Ill Gnaw your bones”. He will do an instakill onthe nearest player.
- When Barz says “No power is stronger then Barz” he will get power from a random character. minstrels should NOT heal while he says this or they will get aggro.
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!
When engaging an opponent check the different effects and buffs of your ballads. For example, for whights it is good to use tier 3 ballad that reduces Fear while this is not useful for humanoids.
Check the different damage type you receive and addapt your attacks to that.
