BRO. THANK YOU FOR THIS. Even with the "noble" art of barrelmancy at my disposal, this fight was insane for me because I have been keeping my honor mode party hamstrung on purpose by keeping my main character out of most fights. I wouldn't have been able to get through this with my three level eights (fighter, cleric, rogue/ranger) without the surprise element and scratch tip allowing me to wail on him before any skellies even made it to the platform. Kudos, bravo, blessings unto your playthroughs. I'm SO GLAD I'M DONE THIS FIGHT.

I just hit act 2 in my honour mode run and am thinking about this fight coming up. The invis for surprise and Scratch to free Aelyn is a great trick. After that, seems mostly like a damage check before things start to get hairy! Oh, and knowing you can skip to the Myrkyl phase with that roll is nice, too. Thanks for the vid!

[destroyercreater]

Oh god no one is ready for what I learned. Fun fact I learned when fighting him.

Remember the ring you get in the Chest at the top of moonrise tower? Well that ring’s command… actually affects Myrkul.

So if you use Command: drop on him using a high charisma character… he drops his scythe and practically loses all of his power.

I’m not messing around. It works.

What really helped me in this fight on honor mode was the arrow of Ilmater. Stops him from healing. Then I threw water on him and hit him with a ton of lightning. Getting Scratch to go to Aylin was genius!

[BeanyBop]

To anyone needing any help with this that maybe did not prep as much as these help videos reccomemd you do. Here are some tips for what helped me on honour mode.

1) have someone, either cast or use a scroll of a wall of fire right across his pit, it does pretty good damage and will help wear him down.
Have your caster be someone with good saving chances so as not to get interrupted.

2) ignore the summons. Just try and focus him with everything you have as hard as you can



3) cast anything which will help you get advantage attacks on him. If you can get something like faie light, moon light butterflies, guiding bolt etc... or anything like that on him, even better.

Fire and radiant damage do well against him.

( for anyone on console ) cheese tip
If you are on honor mode, and your party is about to die, or the fight is not going well. Hard quit your game, go back to dashboard. And reload your game. It will start from last save depending where you saved, but will save your honor run.

This was such an incredible fight for me in honor mode. Only took two turns to kill Myrkul with the darkness and, of course, the wet condition. I look forward to seeing more of your content once I get anxious about all the other bosses 🙏

[PrideOfThLion]

The setup for scratch and the surprise round worked perfectly. Thanks for the strat. Smoked him on round 3. All of this still works as of 12-6-24.

To everyone watching this video: the dialogue will not always trigger this way. It's not a bad set up but be prepared to still fight the first phase regardless. Use the surprise round to free Aylin with scratch and kill the mind flayer.

I completely forgot about the mind flayer and just skipped everyone but Scratch's turn to just get to the dialogue. Mind flayer came down and stunned us all, and my 21 hour run came to an abrupt end 😔

Never had problems with this fight in any other run and I was honestly whooping the game's ass until then. Devastating loss lol.

[chiaoutzu]

Tested this on tactician playthrough before doing it on my honor mode run and initially has issues with triggering the dialogue but figured it was the distance I was attacking from, got it to work on my honor mode run and I totally mopped the apostle of Myrkul. Thank you! 😊

[davidbouchard]

Nice, I was practicing the fight for my honor mode in tactician and started to get scared. Your video prove to be useful. Cant wait to try this!

[GabyT]

thank you soo much you saved my honour gameplay

[Felhek]

This is insane, I barely was able to defeat them all and then this one kill everyone with one movement.
That's totally unfair

[tomaspokorny]

For me the best option to defeat the Myrkul (360 hp) was to cast mist lvl 3 on platform where he is.. Tham you can come to him hit him and than run out. And the necro guys he is sppawning dont wanna go to that platform to heal him.

[YGODueltainer]

Pretty sure they patched it, invisiblity or not. It will trigger the dialogue anyway.

[chinaman]

Monks are fncking OP, even until now.

[talradlandheart]

This was a tough fight for me in my honor mode run but I pulled it off. My main character was a berserker barbarian, so I was able to soak up some of the fears using her. I had Shadowheart on the ground with spirit guardians active to keep the skellies in check since they are vulnerable to radiant damage. His anti-healing aura made it a bit tricky to top off injured characters, but ultimately I managed to get it done.

[kivenpanghulan]

Thanks for the technique! Got him on my honour mode, luckiest part is that I was able to stun him with Laezel! :D

[bugg]

April 2024-Updated to where he only loses his melee attack. He can me harder to kill without his weapon after the update because he will spam his room wide AOE pull which hits for 40-90

[cesarthrashful]

This fight is impossoble for me, i do like two damage to him, or miss every attack and he one shots me and frightens me every turn, its bullshit

[adamek]

bro this fight is so unfair, first they want me to fight kethric who does bombasitc damage with his smite, and now they want me to fight this thing, right after the battle when half of my party is dead?
