Sepulcher of the First Ones - Halondrus Solo (Normal)

Disappointingly easy boss to solo! The orb mechanic can be mostly ignored and in phases 1 and 2 and easily sustained through with low stacks and the tank debuff does not stack infinitely and doesn't hit hard enough at 70 to be a threat.
In the final phase the dot from the orbs can stack very high which can deal considerable damage but is easy to sustain through by using a cooldown or two, and there are so many orbs that it isn't worth trying to do the mechanic properly.

I recently came back to Dragonflight from Classic. Will be doing this raid on my druid this week sometime. Is the whole raid soloable?

[@RPGnutter]

When I tried this during the first raid tier Anduin was a hefty wall - he despawns if you try and go into the Kingsmourne phase and if you ignore it, the Lich King add phase all dealt too much damage for me to survive though.
However I feel pretty confident in saying that even if Blizzard don't fix the encounter to prevent despawns for solo players (KT in SoD has the same issue) that with higher ilevel gear from the 2nd or 3rd raid tiers of Dragonflight that Anduin will be soloable. As for the remaining bosses after him, Rygelon I actually don't really know much about the fight, the Dreadlords will likely be a significant DPS race due to the infinitely ramping DoT, and the Jailer is theoretically soloable but I couldn't be any more specific at this time.
Full disclosure that I have never done any soloing on anything other than a DK so your mileage may vary!

@@RPGnutter well tried it last night and went smoothly up to Pantheon. Just haven't enough damage or interrupts for that fight I think. My gear is only ilvl 410 as I don't do any dungeons or raids anymore. I'll maybe check my talents and see if anything can be improved.

@@TheBlaert I think I was around 410 when I did Pantheon, that was definitely the hardest solo in the instance I managed so far though - I had to talent for shorter interrupt CD and longer AMS duration in order to reset the dot stacks in P2.

@@RPGnutter to be honest it was late and I only really gave it a couple of attempts so I'll give it another few goes this week. I'm only really doing it to get Enlightened rep a little quicker so it's no real loss anyway
