He is behind the tent Friday at 12am.. Hope that helps

tried that 5 times now and cannot find anything, very frustrating!

I don't think it'll come up if you're right behind the tent at 12am, try meditating somewhere else near and just run over behind the tent when the time comes. That happend to me.

thanks for the tips, however still no luck, and we it says 12AM on Friday that means like right after 11.59PM on Thursday? man this Edenia stage is a pain in my @$$, I cant get Lui Kang or beat Tonya so I have nothing to do until then, thanks again!

u have to beat konquest first
i forget but it might be the first of every month

Some tips.
1) Beat Konquest first
2) Wait in front of the tent
3) The chest appears behind the tent on the RIGHT hand side
4) It doesn't always appear at midnight exactly, you sometimes get it a few minutes later.
5) Make sure it's Friday.

thanks guys, i did not beat Konquest first, I guess I will wait until then, any tips on how to beat Tanya so I can free Sindel?
