Perma and Dungeons

I'm new to being a Perma. My Assassin has 45 hours on him. Most of which I perma for SoO.. gets boring, and I would like to be able to do something more.

Kathandrax:
I don't know this run. I have not been through this dungeon yet, and as such, I don't know the map. What I've gotten so far is this:
1. The Perma runs there, and runs to the level 2 portal of the dungeon after the 600 gets the dungeon key.
2. The Perma also sometimes solo's level 2.

I have the builds to do this, someone kindly linked them to me. What I don't know is the run, or the tactics, or any other important things. Because I'm not "pro" or "exp" I can't get into groups to give me a shot at the run. Going in, and dying so I can watch the perma usually gets me yelled at.
So can someone shed some light on this at all?
Thanks in advance!

common sense can help out well

For the purposes of dungeon practicing, you might consider taking a different character in a pug to see how the dungeons are played in HM. If you can afford to pay for a run, just ask permission of the runner to observe. If he says no, there are plenty of other runners. If you can't afford to pay for a run, at least get in a pug so you can see the layout and figure out some of the fights.

Next, you can go to any dungeon with heroes/henchies, and use them the way the runner would use pugs. It will take you awhile, but the point is to train your perma, not the speed of your run. Practice this in NM first, then bump it up to HM.

If you do those things, you should then have the confidence to do a few practice runs for tips. Once you get efficient, you can start charging people. The practice is well worth your time when you consider the prices the runners are charging for the tougher dungeons.

In level 2, all you basicly have to do is gather aggro and hold it for the group to pass through to the shrine and the next room, then break aggro, but you may want to try in a tips run first

Gee Coast....Thanks for the helpful reply. Such a wealth of knowledge.
