i stuck in quest 2, at the point when the gargoyle appears.
anytime i am smashed to death, no matter whatever i do. i have tried everything thats possible, but this enemy can not be beaten. So the game seems to end up at this point for me.

i have also read help-topics within this forum and also in the internet - nothing helped, so the known solutions for this enemy do not work. Does anybody have the same problem ? is it maybe a bug that you are dead exactly at the same time (after about 4 seconds, no matter what you do)

Quests are not numbered, and there are plenty of gargoyles in the game. So what are you talking about?

my english is not good, but i will try to explain:
it is in the second main quest searching for ciri
you are in velen, being in a chamber with keira
and then there appears a golem and right after that the gargoyle which cannot be beaten

Ah, I see. I have done that quest numerous times and the gargoyle is tough but can be beaten. Keira will actually help you. Sometimes she can even stun-lock the thing. Remember: 'dodge' and 'Quen'. You have to hit and run (dodge/roll) and just keep at it. Quen will keep you alive in case it does land a blow. Use 'Elementa' oil on your sword if you have it.

if you use a tawny owl beforehand and quen every time you're hit as well as using hickory's suggestions, you should be able to beat it.
