Journal entry Edit
- Geralt had done what was required. He could now go to the infamous Tesham Mutna, where he would once again face Dettlaff.
- Higher vampires bear an uncanny resemblance to humans. Yet the similarities are only skin deep. We mere mortals have a dastardly time trying to understand their emotional makeup and morals. So Geralt could never have foreseen what happened - that Dettlaff would try to take Syanna's life.
- Luckily, Syanna had her protective amulet. Crafted long before by Artorius Vigo, it did exactly what it was created to do. At the crucial moment, the duchess' sister disappeared, transported to a spot both safe and secure. Dettlaff flew into a rage. He lunged at Regis and Geralt, intent on tearing them to shreds. Yet the duel ended with his defeat and, at the last, his demise.
- Help Regis fight Dettlaff.
- (Optional) Prepare for the fight.
- Defeat Dettlaff.
Combat tactics Edit
First off, when you get past the initial cutscene to the gameplay mode when you see Dettlaff and Regis fighting in the distance, don't move forward yet and save your game. This will be a three stage fight and you won't get any automated Checkpoint saves between them or chances to replenish your potions; if you die at any point you'll have to redo all three stages. This is also a good point to equip any potions or oils you want to use for the fight; note that Dettlaff is immune to your crossbow and any bombs that purely give a status effect, such as Northern wind, so the good old Grapeshot could be your best bet for range. He's also unaffected by Axii and Aard; Quen will be the most useful for you during this fight. Once you've prepared, move towards the fight between Dettlaff and Regis to start the main fight.
Stage 1, Humanoid Form Edit
This is the same form that you faced Dettlaff in when you first tracked him down to the warehouse. He has ranged dash attacks and will usually dodge away after he's taken one hit. Similar to facing Olgierd von Everec in the Hearts of Stone expansion, a short-dodge-fast-attack pattern dodging behind him and doing a quick strike usually works best. Once you've done enough damage he will transform into his next state.
Stage 2, Flying Form Edit
In this form you have to be patient; there is only one point during his attack patterns where he's truly vulnerable. While he's in the air, as mentioned before he's immune to everything you could use to knock him down. His dashing slashes are easy to dodge with a roll, however his bat wave attack can be tricky; you either have to roll with perfect timing or run full speed in a direction perpendicular to him (like you're circling him at the same range), preferably at a good distance away. When he dives down onto the ground and stays there for a bit, this is when you have a precious few seconds to hit him as hard as you can before he flies back up and sends out a short ranged shockwave. Rinse and repeat until he goes to the third stage.
Stage 3, Body Illusion Edit
In this stage when you're in the illusion of the inside of a fictional version of Dettlaff's chest, there are several pulsing hearts around the walls of the chamber. You have to destroy these hearts while fending off the Dettlaff blood clones. The clones can hit VERY hard and destroying them doesn't do any actual damage to the "true" Dettlaff himself, but destroying one can give a few precious seconds of time to focus on one of the hearts until another is spawned. Once you've destroyed enough hearts, Dettlaff is finally defeated.
