Insane Difficulty Boss Guide

Overview

This guide will teach you how to easily kill every boss on Insane difficulty level without getting ploughed!

General Info

• Main focus of this guide is a fast and safe boss fights on Insane difficulty level.
• All strategies work on lower difficulties, except for the Dark which offers even more power to the witcher through exclusive items and have a room for errors.
• All item previews were taken from The Official Witcher Wiki[witcher.gamepedia.com].

The Build

In my opinion the best way to conquer Insane difficulty is to go Warrior-Mage path, you’ll have good crowd control to get out from risky situations, melee and magical damage to slay your enemies very fast and a Group Finisher along with Heliotrope Sign as an extra airbag. Drawback here is a lack of defense, though it doesn’t matter much, since most prominent foes can one-shot you anyway and if you’re playing on Insane difficulty it means that you’re already now what you’re doing.

Here’s an example on how the final build should look like:

NOTE: I will provide build progress screenshots before each boss fight.

NOTE ON MUTAGENS: Since it’s a Warrior-Mage build you wont likely find many (if any at all) greater mutagens, so it’s up to you whether to use basic ones or not. I didn’t include them as an important part of this guide since their acquisition is completely random and effects are negligible.

NOTE ON TROPHIES: Use whichever suits your needs at a given time and be sure to get an awesome end game trophies such as Medal of Distinguished Service to Temeria (Roche Path) and Golem trophy (Iorveth Path).

NOTE ON WHETSTONES: You only have 10 of these and you can’t farm/purchase them in the game, so keep them to use against bosses.

Useful Abilities to acquire

Kayran

Any silver sword will do.

Hunter’s armor (Diagram recieved from the Troll of Flotsam if you returned the troll’s mate’s head to him).

OR:

Raven’s armor (The Witcher 1 save import bonus, available only if it was acquired).

Mongoose (Part of The Kayran: Ostmurk quest, provides poison immunity).

Virga (Formula can be purchased from Vilmos Bartok in Flotsam).

Swallow (Starting potion).

Diamond armor reinforcements x3 (Diagram can be purchased from Sendler in Lobinden).

Make sure to grab Fortitude LVL2 for additional Vigor. Make a choice between Dagger Throwing & Hardiness, I prefer daggers, with them you can easily kill some tough early game monsters, while +10 HP… Well, wont help you much to say the least.
Get Feet Work, it’s pretty important in the upcoming fight, also grab Schemer & Tough Guy. Start investing in Magic Tree by putting a point into Destructive Magic.

NOTE #1: Kayran has 6 tentacles, 2 frontal tentacles cannot be cut, avoid them by running to the sides.

NOTE #2: You can use Kayran Trap here, but I don’t think it’s worth the risk running to a designated spot to put a trap which ultimately just saves you a couple of seconds.

NOTE #3: If you’re not very confident in you dodging skills then I strongly recommend keeping Quen sign on at all times.

1. As soon as the fight unfolds immediately run to the left, dodging first tentacle attack*.
2. Set a Yrden trap and wait in front of it for another attack.
3. Dodge the attack and cut the immobilized tentacle.
4. Immediately after set another Yrden trap and run away to avoid Kayrans onslaught.
5. Again – wait for attack in front of your trap, dodge it and cut another tentacle.
6. Run away again to avoid Kayrans attacks.
7. Next run to the right side, dodging possible attacks from the front 2 tentacles.
8. Set last Yrden trap and wait for yet another attack.
9. Cut the tentacle, run away slightly to avoid last series of attacks and perform QTE.
10. After the QTE immediately run to the collapsed bridge and roll your way up to victory.

* Note that you CAN be killed in a single blow if it hits you from behind.

Letho (Chapter I)

Jagged blade (Diagram can be purchased from Berthold Candeleria at the dwarven smithy in Flotsam).

Hunter’s armor (Diagram received from the Troll of Flotsam if you returned the troll’s mate’s head to him).

OR:

Kayran Carapace armor (Diagram for this armor can be purchased from Berthold Candeleria in Flotsam).

Thunderbolt (Formula can be purchased from Fioravanti in Flotsam).

Rook (Starting potion).

Wolf (Formula can be purchased from Anezka in Lobinden).

Whetstone (Starting item).

Ysgith rune x2 (Diagram can an be purchased from Berthold Candeleria in Flotsam).

Diamond armor reinforcements x3 (Diagram can be purchased from Sendler in Lobinden).

Key to the next fight is a constant pressure and for this you’ll need a lot of Vigor, so make sure to invest another point into Destructive Magic followed by Enhanced Quen Sign and Magical Vigor.

1. Go ham on Letho right at the start, don’t let him castQuen on himself.
2. Initiate fight with Aard -> 3 Heavy Attacks, try locking him in the left corner.
3. Repeat this combo* until you run out of Vigor.
4. Letho will be out of health by that time, just back out and wait for the cutscene, be prepared to dodge his magical attacks or bombs in the meantime.

* Position yourself according to his movement, you must be always close in order to connect every attack.

Draug

Blood sword (Found inside a chest in the southeastern chamber in the Tunnel of the Founders beneath Vergen).

Zireael’s armor (Given by Dethmold during the The Blood Curse quest).

OR:

Dragon scale armor (Sold by Mael on Rhundurin Square in Vergen).

Whetstone (Starting item).

Ysgith rune x3 (Diagram can be purchased from Berthold Candeleria in Flotsam or Haggard & Thorak in Vergen).

Diamond armor reinforcements x3 (Diagram can be purchased from Sendler in Lobinden).

You should be pretty buffed up at this point and next boss fight will be extremely easy. Rush through the skill trees to get both Adrenaline Skills and invest 2 points in each Whirlwind and Control over the Power respectively. This yields massive adrenaline generation, really pumps up your resistances, adds magic damage and improves critical chance on everything including signs.

NOTE: Once you enter the mist – any effects of the potions/oils and other buffs will be reset. This effectively makes it impossible to drink any potions beforehand. But you still can use Whetstone once you get control over Geralt during the Draugir fight, just don’t forget doing so.

1. Unsheathe your sword and immediately cast Aard on Draug followed by 2 Heavy Strikes*.
2. Repeat this 2 more times and he’s ploughed.

* Draug can start teleporting right of the bat, don’t risk it and just reload the latest autosave if that occurs.

Dragon

Deithwen (Can be looted near a ruined wagon, a short distance past the entrance to the caves east of Loc Muinne).

Armor of Ysgith (Can be looted from a locked chest in the northernmost part of the Sewers of Loc Muinne).

Thunderbolt (Formula can be purchased from Felicia Cori or The Incredible Lockhart in Loc Muinne).

Rook (Starting potion).

Swallow (Starting potion, to regenerate possible incineration damage).

Whetstone (Starting item).

Ysgith rune x3 (Diagram can an be purchased from The Incredible Lockhart in Loc Muinne).

Magic wrap x3 (Can be purchased from Bras of Ban Ard or Falas in Loc Muinne).

You should be maxed out by this point. Grab Violence LVL2, max Combat Acumen & Sense of Magic abilities, upgrade critical effect abilities such as Energy Flow & Finesse. Max Igni to easily dispatch groups of generic enemies.

1. After you dealt with de Tancarville cast Quen on yourself and run towards the wall from which Dragon breaks in, position yourself slightly to the left so that you can hit Dragons head immediately.
2. As soon as Dragon breaks in – pummel his head with a continuous chain of Heavy Attacks*.
3. You’ll be able to drop his health down to zero which will trigger a cutscene.
4. Climb up on top of the tower, re-cast Quen and wait for the Dragon to appear.
5. Switch to Igni and finish him off with a single fireball**.
6. Perform the final QTE.

* Dragon will fight back, but it doesn’t matter since his melee attacks cant reach you here, just be sure to cast Quen, its Insane difficulty after all and if something goes wrong he still can one shot you.
** Don’t try fancy things like sword finisher or something like that, Dragon has some weird invincibility frames against melee attacks and remember that he can plough your awesome run in a single hit.

Letho (Chapter III)

Dancer (Can be found in the Werewolf Cave while escorting Brigida during the Crown Witness quest).

OR:

Caerme (Reward for An Encrypted Manuscript quest).

Armor of Ysgith (Can be looted from a locked chest in the northernmost part of the Sewers of Loc Muinne).

Thunderbolt (Formula can be purchased from Felicia Cori and The Incredible Lockhart in Loc Muinne).

Rook (Starting potion).

Wolf (Formula can be purchased from Felicia Cori in Loc Muinne).

Whetstone (Starting item).

Ysgith rune x2 (Diagram can an be purchased from The Incredible Lockhart in Loc Muinne).

Magic wrap x3 (Can be purchased from Bras of Ban Ard or Falas in Loc Muinne).

You’re still maxed out, yay. Second fight with Letho will be even easier since you’re a powerhouse now and developers decided to leave Letho on the same power level as he was before, so this fight be pretty much free.

1. As before – go straight up ham on him:
   Aard -> 3 Heavy Attacks -> Aard -> 3 Heavy Attacks.
   This should be enough to outright kill him in just 6 blows.

The Operator (OPTIONAL)

NOTE: This boss is 100% OPTIONAL and also – very hard to kill (at least compared to the other bosses). Only attempt this if you’re 100% confident in your witcher skills!

Caerme (Reward for An Encrypted Manuscript quest).

Armor of Ysgith (Can be looted from a locked chest in the northernmost part of the Sewers of Loc Muinne).

Brock (Formula can be purchased from Felicia Cori or Marcus in Loc Muinne).

Rook (Starting potion).

Wolf (Starting potion).

Hanged man’s venom (Formula can be purchased from Felicia Cori or The Incredible Lockhart in Loc Muinne).

Dancing star x2 (Formula can be purchased from Felicia Cori or The Incredible Lockhart in Loc Muinne).

Ysgith rune x2 (Diagram can an be purchased from Cerdric in Lobinden or Earso in Loc Muinne.)

Magic wrap x3 (Can be purchased from Bras of Ban Ard or Falas in Loc Muinne).

Level 32 should be enough to deal with The Operator, the key to this fight is critical effects of signs, so max out Energy Flow and don’t forget to visit Winter Shrine outside of Loc Muinne to get Winter’s Shroud perk which will also be very helpful.

NOTE: Be sure to get an additional attack boost by visiting Circle of Strength which located near the stairs leading to the Count Maravels room.

NOTE #2: Again – if you’re not good at dodging and/or positioning then try to keep Quen on yourself at all times.

NOTE #3: Fill your adrenaline bar before venturing into this fight and use Heliotrope Sign when/if in danger.

1. The Operator always greets you with a fireball, dodge it and then hit him with
   1 Fast Attack -> 1 Heavy Attack*, roll out and then cast Aard on The Operator.
2. Wait for the Gargoyles to spawn**.
3. Start clearing first wave of Gargoyles by casting Aard and poking them with a single Fast Attack***. Don’t forget knocking The Operator down with Aard constantly to prevent his fireball attacks.
4. When both Gargoyles are dead, knock The Operator down again with Aard and throw 1 Dancing star at him****.
5. It will incinerate him a few seconds after, wait meanwhile, regenerating your Vigor.
6. When his health drops low enough another wave of Gargoyles.
7. Knock The Operator with Aard yet again and start killing those pesky Gargoyles, strategy is the same as before – Aard -> Fast Attack poke, repeat until they both dead. Don’t forget about The Operator – knock him down or just dodge his fireballs.
8. Once you dealt with Gargoyles knock down The Operator with Aard and thrown another Dancing star at him.
9. Now you can start working on his shield, a couple attacks will do, while he’ll be busy burning – finish him off, alternatively you can just spam Igni with your remaining Vigor until he dies.

   * This combo will tear most of his health, so he’ll put shield on himself immediately after.
   ** If both Gargoyles spawn near or even behind you – don’t risk fighting them, just reload your save since they can instantly gangbang you in just half a second. F9 is your best friend here.
   *** The key point here is to proc Aards critical effect to stun/freeze the Gargoyles and instantly finish them off. Caermes 4% insta-kill chance helps here as well. If you run out of Vigor before killing first wave of Gargoyles then just F9, no sweat, better safe than sorry.
   **** If you kill a Gargoyle near The Operator it will set him on fire immediately due to their innate ability to explode upon death, saving you the need to throw Dancing star at him.
