Very easy to get these for all your guild's bards and warriors!
Echo of Nortlav... Very fast mini-raid/take down for a guild raid of 2 or 3 groups of 60s. Here's my experience with it.
To get there... Run your folks through the Panieel stone in PoK, go into the city, right by the zoneline is a cliff group up 5 guildies, click your DA (60) song and have those five immediately jump, mid fall they will zone into the Hole and most of the time they will land right next to Echo of Nortlav in a big room with a pool and waterfall. Sometimes they during the fall and DA wears off and they die. Good news is Clerics get DA and can jump down ahead of folks and rez if needed. I've done this 4 times and died half the time due to lag.
If you and your raid stay near the pool's edge, nothing should aggro you. Nortlav won't aggro til attacked. If you do get attacked, it's normally a gargoyle or two and a partial raid force can easily dispatch them. Careful of playing AoE mana near the walls as I aggro'd mobs that way. They come through a hidden door.
Ok for Nortlav, he's level 51 with wimpy hps, and ALWAYS drops the red scale and a cool Erudite SK only weapon. That's the good news. Bad news is he has a wicked 1500 pt lifetap that he procs regularly. That not only drains cleric's mana but heals himself something fierce. That calls for quick fights so DPS is good here. When we've succeeded, we've taken him down in less than 1 min. Longer and we wipe. He's doable for longer times but it may be harder. I like having a Pally tank to use their Sanct disc and have a couple chanters there to chain rune the MA. Otherwise, just KEEL.
Lastly, bring porters, it's not fun getting out without one. When I got mine, I offered to sacrifice my druid by jumping in, getting a rez and porting folks out. Bring a porter/TLer hehe.
This encounter is IMHO much easier than some of the other ways to get the red scale because he's static, and reliable. He's on a 6 hour respawn. We've done him twice in one day before. Just camp a mule in that open space, log him on and if he's up, go take him down. Hehe I have a Erudite SK sitting there to check and next time we take him down, he's getting twinked with a cool sword...
GL getting your scales!
