I spend 6 days at Lower Guk. The first 3 days I spent looking for people to help me fight at the Elder's Room. Getting to the Elder's Room is very hard. It took me 1 day to figure the location out.
I would shout for forming an Elder's Room grp, but nobody wanted to come, and if they did, they didn't know how to get there or affraid of the Gargoyles. (Best thing is to form the grp at the Bedroom and work your way to the Elder's Room)
On the 4th day, I decided to fight at the Bedroom. I met many different players, by the 5th day, I was still in the Bedroom with a new lvl.
On the 6th day, I started a grp with one person. He was a 46 war. He knew some players and began to bring them over. When we found Raster we had two monks and a druid. (Monk 1 was 49, Second monk 38 and druid was 44). We took the room well, sometimes when a train arrived we had problems, but we were able to get out of it.
We used the despawn method. It is very funny that the mob will disappear at around 8am (EQ time). Then another mob or Raster would show up.
What puzzled me was that Raster appeared at 10PM (EQ Time) TWICE! And one time after respawn.
So, try it out, don't kill the place holder (the mob that is holding the place for Raster). Let him stay until he disappears at 8am EQ time, then a mob appears, kill that and wait again until another mob appears, and wait until it disappears and see what pops out.
In 1.5 hours we saw Raster 3 times!
Good luck.
