I think that would depend on the dungeon, some are easier than others. You can solo normal dungeons, people solo vet dungeons too, not sure about doing it at CP300 though.

Yes its possible, but it will take you time.

As a CP 370-something player, (aye, 'tis quite bad that I don't even know my own level ...), running a mid-tier, fairly mediocre PvP Magicka-Sorcerer build, I'm able to solo most 4-man Dungeons on regular difficulty; using a PvP build, my self-healing is more than adequate to keep myself alive, my shields compensate for the Health I don't yet have from the Warrior CP Tree, and my damage is adequate for dealing with pretty much everything that I face. On average, it takes me between 15-25 minutes to complete most Dungeons alone, which is bearable, albeit not very impressive. However, while I haven't tried it, I highly doubt that I'd be able to make it through Veteran Dungeons alone, especially the ones that I find to be quite tricky, (Tempest Island, for example).

As others have said previously, solo'ing Dungeons isn't nearly as fun as it is doing them with other people. Moreover, for me, there's no sense of achievement at the end of it - it just feels that my very soul has been doused with butyne, ignited, dragged through a 3-mile-long stretch of thick gorse bushes by seven heavily barbed, rusty fishing hooks, rolled up in sandpaper, and thrown into the fiery abyss of Mount Doom... ...I find solo'ing 4-man Dungeons to be quite draining, especially when grinding for gear. Speaking of which, unless you're really stuck for company, don't try to solo-grind for gear in Dungeons; compile a good group and complete it on Veteran difficulty, as items found will be Purple instead of Blue, (which is massively helpful with regards to Jewellery), and if you don't find what you need, there's a chance that another player in the group might have.

But I digress... ...yes, at your level, with a suitable set-up, it should definitely be possible. The build that I referenced really is mediocre at best, and I've succeeded in solo'ing every 4-man Dungeon that I've attempted, ("Every...", meaning most in the roster). Of course, if you're new to certain Dungeons, you may have to dispense with 2-or-3 Soul Gems as you learn of the weaknesses and strengths of a certain boss, but you'll get there - good luck, try to enjoy it, and I hope that you're able to achieve your goal!

There should be a few normal dungeons that you'd be able to solo, assuming that you have a reasonable build and decent gear. Banished Cells 1, Fungal Grotto 1, Spindleclutch 1, Darkshade Caverns 1, Elden Hollow 1, City of Ash 1, Wayrest Sewers 1, Tempest Island, and Arx Corinium are definitely soloable (I've done them with a Magicka Sorcerer, no pets). I'm positive I've seen posts saying that the others are as well. I think the only basic dungeon that absolutely requires at least 2 people is Direfrost Keep, but there may be ways to glitch through that part (not sure, never tried).

I play a stamplar ... and I can solo 4-man dungeons (those named before (the "one"-versions) and some of the "two" versions like wayrest 2, spindleclutch 2 are soloable ). If I can do it, you can too

Soloing normal dungeons is ok / doable - but its a SLOW way to get Undaunted if that's your goal. You would be better to get a team of 4 and do them on vet. Doing hard mode, no death, speed runs and that unlocks Undaunted the fastest possible way.

How hard is it to solo the Malubeth fight?

Edit: I see somebody else beat me to the same question.

If you mean 4-man dungeons, then you can possibly clear them, BUT there's at least 1 , maybe 2 that require 2 people. It's a mechanical feature. ( Apologies if this was already mentioned.)

Anyone know which dungeons cannot be solo'd because of mechanics?

(Edit: Direfrost .. @PurpleDrank already mentioned this.)

In addition to that, there are a number of fights where one character gets disabled for a period of time. I have no idea how to solo Blackheart Haven, and soloing Fungal Grotto 2 would seem to require learning the timing and dropping an ultimate before you get picked up.

add Vault Of Madness in the list,solo it recently, only watch for Ulguna Soul-Reaver
other bosses are easy if you pay attention to mechanics

4-man dumgeon Normal , sure.

4-man dumgeon Vet, not impossible

12-man Normal Trial, might be kinda hard

12-man Veteran Trial, id be very impressed

Most non-dlc dungeons can be soloed on normal. A few can't with mechanics that have you pinned to something or unable to move, mainly Crypt of Hearts 2 and Fungal Grotto 2. I just say have a form of self healing.
