Can't defeat Kaileena in throne room; bugs?

[gulfcoastfella]

Hey,

I've been trying to defeat Kaileena in my first fight with her in the throne room. I feel like every bug in the game is rearing it's ugly head for this one battle, and I haven't been able to defeat her yet. When I tell the prince to jump away from her, sometimes he'll instead jump straight towards her. The camera work is atrocious. The biggest problem I've encountered so far, though, is that one time I got her down to about 1% health, and then she just stopped taking damage. I tried to get her down to 0%, but the attempt took so long that she was able to land hits on me, exhaust my remaining sand tanks, and kill me. And her health never dropped below that 1%. If anyone can enlighten me about what the heck is going on, I'd greatly appreciate it.

Hello gulfcoastfella thanks for getting in touch with us.

Another player contacted us previously about the same boss fight when having issues trying to complete this. They told us the following fixes worked for them, could you please try the following >

As the game is one of our older titles released on an older Windows OS, try running the game using 'Windows compatibility mode' to emulate an older Windows OS and make sure to select 'disable full-screen optimizations'. Please see our guide on how to enable this > https://www.ubisoft.com/help?article=000063445

In case this issue is caused by a corrupted game file, please try verifying the game's files in Steam to see if it can fix any affected files and resolve this >
