Hello eso forums, after watching @Vaoh do solo vet white gold tower (something I thought was impossible) I went about trying to claim the achievement of soloing a dungeon that was thought to be impossible as well. I decided on vet fungal grotto 2 for 2 reasons number 1 being that it had not one but two group mechanics (chains 2nd boss, cave 4th boss) and the second reason was that I already had a small idea in my head that it might be possible because I tried 2 manning it with a cp 140 friend as his first dungeon (yes lol) and he was having trouble getting me up in the chains so I had to help him out by making sure i had some aoes on ground before being chained.
Now let's talk about how I went about it, In 1 tamriel we saw zos increase the health of vet dungeon enemies to effectively twice the amount of what it was before but I did not let this discourage me because now we have access to grothdarr and the destro ulti. these 2 combined with power surge passive heals on my aoes are the reasons why this is possible. The boss doesn't have a designated area which she isn't supposed to leave so this means I can fight constantly while I have ulti then use it right before she chains (she chains in timed intervals which I learned the timing for everything) then right before she would chain again while I have no ulti I kite her away to another area and she goes into her clone mode where I recharge ulti or the next 2 phases (the clone phase is also timed) this means this boss is barely soloable it took me around 10 hours to discover how to do it, test out different sets and skills and then to execute on it.
The only other hurdle was going to be 4th boss which is the spider boss but she has a HUGE amount of glitches to avoid the cave, I went with hidding behind tree to the left of bridge which made me not get sucked into the cave and not have to deal with laser.
These fights except 5th boss are all not recorded entirely this was completely out of my control as xb1 only allows recording videos of up to 5 mins each. I did not record 1st or 3rd boss since they are so easy they aren't even worth it, they do nothing except be damage sponges.
