Killing The doctor EASY

This is a Step by Step guide on how to destroy the doctor easilly as any character or any class.
WARNING: way easier with a friend and requiers at least 1 follower.

Brief Overview

So, the Doctor is a hard fight, probably the hardest fight in the game. After our party of four friends got blown out trying to beat him the normal way, we started looking for a workaround. We tried crates of Deathfog, but the Doctor and his companions were immune. In the end, we realised that we could beat him and his companions by utilizing his AI and pathing against him. So here's how to beat the Doctor with the power of art and ♥♥♥♥♥♥♥♥. (All this was done at lvl 20)

Requirements

Time, tenacity, and lot of stupidity. Also, like 40~ paintings. A party member with high max carry weight, access to Kemm's vault, co-op friends, and a party member with telekinesis would be helpful.

Preperation

When you first meet the Doctor, he will have a forced conversation with you and make you an offer to join the dark side or some ♥♥♥♥. When you reject him, because he is a nerd, he will then kick you out of his house. Any subsequent times you go into his room, he will force a conversation, then aggro on you.

In any case, avoid stepping in his room. Save frequently in case you mess up. The first thing you will want to do is get a ♥♥♥♥♥♥♥♥ of paintings. There are plenty in the Doctor's house and in Kemm's vault. Painting of a Landscape and Painting of a Battle are particularly useful due to their high health and large size.

Get all the paintings and stack them in all the doorways of the Doctors room kind of like thisThe AI pathing in this game is good, but not good enough. The Doctor and the demon buds he summons will find themselves unable to get through your painting barricade. Make sure there is absolutely no way to get through. After an extended period of time, the Doctor will begin using melee attacks to tear down the paintings, but unless you take a ridiculous amount of time with his lackeys or didn't put enough strong paintings in, this is not an issue.

!IMPORTANT!: Beside the main entrance to the Doctor's room, at the very back of his house, is a small doorway. It is hard to see because it is covered by a curtain.
We didn't see it when we first used this strategy and didn't block it with paintings, but leaving it uncovered turned out to be a blessing: one by one, the Doctor's demons slowly figured out that that path was barricaded and filtered over to us through it. This was incredibly useful as it allowed us to deal with the Doctor's demons far away from the Doctor himself. As the Doctor fights you in his true, giant demonic from, he cannot fit through the gap.

Combat

Be sure to initiate combat in the room opposite from the Doctor's. The goal of the painting strategy is to isolate the Doctor from his companions and kill them first, robbing the Doctor of the stat buffs he gains from his permanent "Thick of the Fight" buff(stat increase for every nearby unit).

Focus the nurses first. They are squishy and provide buffs to other units.

If you correctly set up and left the curtain door open, the demons will slowly trickle to you, where they will be easily killed.

Beware: do not get to close to the painting wall. The Doctor can shoot spells through it and though AI doesn't cast spells on paintings, the paintings can be damaged collaterally. One stray fireball is all it takes to ruin the plan. Be wary of oil surfaces and large aoe spells that randomly effect surfaces, like Earthquake.

Additionally, stray to close to the wall and the demons will come for you immediately.

Destroy the Doctor

This guy ain't ♥♥♥♥ without his friends. Kick his ass.

I killed all companions first, without talking the doctor. You can kill them one by one and by archer and run to an exit after killing. It will stop the fight. Then you can kill all companions an then talk to a doctor. He will fight alone.

Or you could prebuff Peace of Mind then combat, Apotheosis into Adrenaline into Cloak into Mortal Blow into Skin Graft Into Cloak into Mortal Blow.
