Just looked at the resource requirements for TH8.
To upgrade everything at TH8 you need:
98,048,050 gold (excl. walls)
65,048,550 elixir (incl. lab)
382,500 dark elixir (incl. lab)
128,560,000 gold for walls
394.58 builder days
143 lab days
This is great info igbomb -- was about to start compiling this myself, but did you find a source that has this outlined?
I'm going to make the TH9 plunge early, just not sure how early yet. At this point in the game for me, it's become all about DE, and being TH9 will net you so much more, I'm willing to take the risk.
I found a spreadsheet on reddit. Here is the
link.
It's a bit out of date (looks like the last few updates are not included) but it helps understand the scope.
And this is for culdeus:
TH9
Gold: 192,366,550 (excl. walls)
Elixir: 90,448,550 (incl. lab)
Dark Elixir: 4,747,500 (incl. lab)
Walls: 1,020,530,000 (that's BILLION)
