As i promise movie of how to make rebirth quest:
seems like you need click 3 times each bar to make the each step of quest that require:
- 100 % of exp (first step)
- 100 milions of coins (second step)
- 10 000 of national points (3rd step)
to get 2 stat points that are added to your max 255 and white wings above your name
Also if you are overweight or your inventory is full you wont recive rebirht scroll - so better check your inventory before you try to finish quest.
