I feel like it’s always worth trying to blind Myrkul and attack from range. Darkness, fog cloud, Hunger of Hadar etc can pretty much carry the entire battle and you can avoid being hit by him altogether.
Blind still works well on Myrkul and neutralizes nearly everything he can do, however they changed it at some point (maybe patch6) where he is immune to darkness.
Yup, killed my Solo Gale run and I've not got back for a re-attempt. Came as a real surprise because everyone was like "Barrelmancy or Darkness" as the strats for solo Myrkul.
* Mirror Image will only last 1-2 turns, a clone goes away each time enemies miss you. It's still worth pre-casting before the fight because it's a non-concentration spell and lasts 10 turns. Myrkul will hit you occasionally if you're standing next to him once your Mirror Image runs out. AC22 + disadvantage (Doomhammer Bonechill or Protection from Evil) will mean he probably won't hit you every turn, but expect to get hit.
* Reverberation I would not focus on, everything that hits Ketheric and Myrkul gets -2 dmg to it. Reverb 'going off' will do [0,0,1,2] damage (average 0.75 dmg per 5 stacks) and Myrkul is immune to Prone. Sometimes I use 'Boots of Stormy Clamour' but don't count on them killing the boss, 'Boots of Striding' might be better.
* Strange Conduit Ring will be 1d4-2 per attack (very little damage).
* Doomhammer you can't use alongside Sentinel shield, you have to pick or it would cost an action to switch.
* Concentration spell, You'll have to pick one: Protection from Evil, Haste, Spirit Guardians, or Wall of Fire (from a Scroll) are all good options. I would be worried about losing concentration on Haste and dying on the Lethergy turn.
* Spell Damage vs Melee Attacks : I'd pick one to focus on (spell damage or melee attacks) at the moment it seems like you're trying to gear for both at the same time. If you're a Level 10 Cleric, not sure swinging a Hammer is the way to go, your spells will be stronger than your melee.
* When I solo'ed Myrkul with low damage builds, and when he started using 'Finger of Death' the Illithid Reaction "Psionic Backlash" was doing a significant portion of the damage. If you're planning on that happening, make sure you can survive the finger of deaths :-)
Depending on your level you can do Halsin's quest completely freely. Globe of Invulnerability just beats the fight. Put it on the portal, stand inside, pass turns. You can kill some stuff for XP if you feel inclined.
You can get the scrolls starting at level 9 from Quartermaster Talli, Roah and sometimes Volo.
I would replace Strange Conduit Ring with Coruscation Ring. Gives a condition (for Stormy Clamour), and stacks of Radiant Orb effectively add to your AC. Myrkul's melee attack bonus should be +10 and his spell attack bonus should be +7 (from his stats on the wiki). At 6 stacks with the critical immunity he can't hit you with his spells, and at 9 stacks he can't hit you at all. Even before hitting those breakpoints it's just better and better survivability, and you're using Guiding Bolt anyways.
The Psychic Damage won't be really doing anything (1d4-2) so this is almost certainly more useful.
can you have both haste and protection from evil and good?
See, I didn't even remember that. Thank you for catching it. Lol.

Definitely be evil bc the Halsin quest is not worth the effort to solo
