Okay so here is my problem i cant kill kayran simply because when i get on his tentacle near the end of the fight nothing happens no matter how much i spam my left mouse button i have seen a similar topic here where someone uploaded a save after kayran was dead i tried using the link he provided but the files were already gone so if someone could please take my saves and beat the boss for me and than upload ,i know it's too much to ask but i dont really have any other choice since i already tried almost all the solutions posted here about that bug and nothing seems to work so anyways here is my saves

Ooopsie, you're in the wrong forum.
You should post this in the The Witcher 2 forum

Oh,my bad..sorry am new to these forums.
Could someone delete this thread plz?

Don't worry, nobody really cares:P If your problem gets solved, here or on the Witcher forum, remember to mark the solution.

Is it really a bug? Because Kayran fight is actually very confusing for first timer. The game will prompt you a quick time event after you successfully cut off 3 of the kayran tentacles.

Ye it really is a bug i already watched like 5 YT walkthroughs i know how you are supposed to beat this boss i have no problem chopping off the 4 tentecales my problem is with the 2nd QTE
when geralt jumps on one of the remaining tentacles and you are suppose to just keep spamming your left mouse button till you are asked to press space but for some reason no matter how much i spam my LMB the space bar never appears and i get tossed to the ground..it's extremely frustrating,but thx for the advice anyway (:

You could try going into in-game options, there should be something like simple QTEs or easy QTEs or something like that... It basically skips all QTEs except for fistfights.

I already unchecked the Difficult QTE and it doent really help since it doent skip the part where am bugged,but thx for the advice anyway.
