Boss dead or not?

[victorgrant]

Hi,

The Guardian was already with 0 HP but in his invulnerability phases when he killed me. GGG is it ok?
To me not. He suppose die immediately he had 0!!! hp. Probably this fucking phases invulnerability
will be last nail to my leave game in future.

Please help.

I didn't find the right solution from the Internet.
