How to kill Katakana? (The Witcher 3: Wild Hunt)

Doormite bomb, it blocks HP regen

I used the igni and then hit it, then you have to set it on fire again. It also seems that the dream of the dragon helps, but I'm not sure. (I play on 3 difficulties)

Yes, most of the monsters on the pumped ignit can bring down the attack or something else from the cast

I play on the highest. Passed the 10th attempt. It turned out that this is one of the few monsters that can be called with a quick attack, using an "almost" basic quen. It's a matter of chance, because Triss very successfully knocked down his attacks and I managed to squeeze him into a corner.
It’s not bad to dodge the blow with a rebound to the right / left, and then hit the hat. I managed to roll behind him during a marathon. As long as it is semi-transparent, the damage also goes.

I don't know how you are so rushing. It regenerates for me even when I bombard the whole room with ability bombs. I beat him - he regenerates from me. I don't hit him - he just regenerates. Triss is useless

FOSTER_ok
regen is interrupted by a trap, and if you didn't max it, it's a completely different story (black blood to the rescue)

No, in the end he calmed down, drank energy regen, and kicked him with quick blows under aard. Dropped - beaten - dropped - beaten. That turned out to be easier.

You have to use qen(kwen).

And vampire oil.
