Ok when is it a good time to kill vivec and still not break the immersion? I was playing with ghd mod before it broke on me and im gonna try to finish the game off but I wanna kill ur and all the tribuneral. Now I have not finished the main quest before so is vivec still around ingame after tribuneral is done with?

When do u believe is the best time to be able to kill vivec?

I like to complete the main quest and tribunal before leaving Vivec for last.

i slew him after i beat tribunal, i think it gives him a few more lines of dialog, or maybe killing him gives alma a few new lines, i don't remember anymore.

And yes vivec still floats until you kill him
