When could I solo crawl these dungeons?

[kingpinner]

Hey there, I've been making some solo dungeon crawl videos as I level my enchanter up and I have a list of lvl 50+ dungeons that I would like to tackle in the near future.

I'm not sure about the best level to begin attempting the crawl on some of them though. I know many of these higher dungeons won't be able to be taken down completely solo, but the goal really is to be able to solo crawl as deep as possible, earn experience, plus take out at least a couple named mobs.

I would love to hear your opinion on what lvl is an appropriate start to try and do my solo crawl for the following dungeons. It's been about 20 years since i"ve made it to this point in the game so I forget most of these dungeons plus some I've never even been to when I played in live.

Here is my list of zones I'd like to solo crawl and the level I plan on attempting them (mostly just guesses by studying the wikis)...

Karnor's Castle - 53
Howling Stones West - 54
Velks - ?55?
Howling Stones South - 56
Dragon Necropolis - 57
Chardok - 58
Seb - 59
Siren's Grotto - 59
Planes of Hate/Fear/Mischief - 59/60

I would love to hear your opinion on appropriate level ranges to attempt the solo crawl or even if some would be impossible to crawl. Like the planes... I don't know if soloing is even possible in those.

Any thoughts or info about the zones (or if I'm leaving some out that I could attempt) would be greatly appreciated.
