All 4 pillars can be shot from the ground without opening the door. It's completely safe.
People make this quest a lot more difficult than it really is.
Agreed. All 4 pillars can be ranged from lower level, although it takes awhile on EE unless you have a few monkchers.
Best approach I have found is to turn off auras/effects, Mass Invis and Zerg thru the inside mountains parts as much as possible. There are some obvious stopping points of course, but you can avoid a lot of trash mobs this way and speed up your runs to about 40-50mins from memory.
I try to save the shrine immediately after the Mythyllar, before you head outside as you can come back for it if needed.
Once outside, you can mass Invis & Zerg, but we usually don't as you need to stop at a few spots to take down the pillars. Also, if anyone dies and has to come back from that shrine, it helps to have a safe path back to the top.
The shrine before the ramp is use it or lose it, so use it up.
If you die or run out of SP during the final rounds up top, you can drop down at the right spot and head back into the mountain to use that shrine you saved.
If you have plenty of duped sp pots - don't bother, up to you.
As someone suggested, Amskar does have tiered HP - you can and should bring him down each time he appears, but you cannot progress until you kill the trash mobs for each round and some re spawn, so don't flaff around. Best approach I have found is pulling them back to ramp in small groups where CC and group is waiting. Shadovar & boss can be a bitch with meteor swarm and chain lightning that hits hard on EE. So grouping up has its risks.
I have seen strategies to kite the mobs away, but you have to kill them anyway, so that just prolongs the pain unless you have some static damage like BB or clouds to kite thru.
There is one safe spot I know of, which can be used if you don't have a full group or the group is a bit underpowered, but it does make the quest a bit tedious. A good strong group won't need it.
If Amskar is teleporting around like that retarded boss in DA, then it is usually a good indication that you have a mob to kill somewhere before you can progress.
For that final lag inducing wave of insanity, fury shot Amskar and then jump off onto the lower levels.
Collect loot, rinse and repeat.
