This achievement will require some grinding.
You will need to climb to the top of the temple.
To do that you will need to maximize the yellow bar/Strenght.
It will take 4.5 times to complete the game.
I completed it 3 times (Normal, Normal+, Hard+) plus eaten 113 silver tail lizards plus 12 times I killed 1st and 2nd giants (Normal+).
