Public Instance: Sarnur

Entrance to Sarnúr

Sarnúr is a large cavern in the ruins of Orodost, not far from Thorin's Hall in Ered Luin. There is a Dourhand dwarven stronghold, but below are caves filled with trolls and creatures that like the cold, including a dragon. It is a public dungeon with mobs between level 45-50 and a great place to get Thorin's Hall rep (tokens drop from most mobs) and complete some deeds. 

There are several quests available from NPCs in front of The Blue Garrison in Thorin's Hall that give rep. You can reach kindred with Thorin's Hall in a few hours (the goat may be useful in Moria!). There is also Ancient Iron/Ancient Silver and beasts drop Exceptional Hide. Lots of Master (tier 5) recipes drop as well.

Many of the mobs are resistant to any damage type except Ancient Dwarf, so it would really help to use an Ancient Dwarf type weapon. Most mobs also respawn fairly quickly so keep moving. Safe spots to rest are near the entrances to the Great Hall and the Keep.

Sarnúr Great Hall

The Great Hall

The entrance level can easily be soloed as it has single or small groups of Dourhands, hendroveil and cave claws (level 46-47). Northpaw is a rare stealthed lynx that patrols and is resistant to most damage except Ancient Dwarf. Latub is a rare goblin that can spawn near the bridge in the middle of the Great Hall, or near the tunnel or stairs leading down to the caverns.

Sarnúr Keep

Sarnúr Keep

In the northwest corner of the Great Hall are some large doors leading to the Keep. Inside the Keep are more Dourhands, plus wargs and goblins (level 48-49); they are resistant to most damage except Ancient Dwarf but can still be soloed. Faded parchments for the quest "Gathering Ancient Scrolls" can be found in the main chamber and downstairs.

There is a tunnel on the right of the entrance that leads up two floors with some chambers and narrow ledges, but ultimately dead ends.

There are stairs on the left of the entrance that lead to a cave with the Forge of the Blue Dwarves. Beware the freezing water!

Glúmir is a rare Dourhand that has several spawn locations (dead end tunnel on the left, in the lower cave near the water or on the stairs overlooking the hallway). Defeating him is the objective of the quest "Retrieve the Rune-shards".

Sarnúr Caverns

Caverns

On the right of the Great Hall is a tunnel guarded by Dourhands that leads downstairs. This area is recommended for fellowships as the mobs are in larger groups and there are more elites.

In the first chamber there are some Dourhands and cave claws fighting some elite Snow-Trolls (level 46-47). Clear out the Dourhands and cave claws then you can kite the trolls if needed. Watch out for their stun and knock back attacks. There are two quests requiring defeating trolls: "Dispatch the Snow-Trolls" and "Cleanse the Ruins of Sarnúr".

The tunnel continues down and opens into a large area with a shallow river and elite snow-trolls, snow-beasts and snowbears. This area can be seen from the Great Hall as the bottom floor.

Gâdhâp is an elite level 48 troll who may be guarding the bottom of the tunnel, or patrolling the bridges. Icerender the Snowbeast is a rare level 47-48 elite master that can be found near the river. Brúllug is a rare level 49-50 nemesis of a drake who flies and patrols the caverns. These rares are resistant to most damage except Ancient Dwarf. The fellowship quest "Defeat the Cavern Horrors" asks you to defeat either Gâdhâp or Brúllug.
