For players who want to used gems effectively & timeline.
last step can be achieve by the last 24hours Just need to plant 8hrs food x6 in advance & 5hrs later. If you have 2 or more nest it is easier for hatching
Now this is the area we need to focus on if you can afford 150gems this quest & Cancer is a walk on the park for you.
[3.1] Hatch Knitten Kitten(dark / earth) (50 skip)
[3.2] Feed Knitten Kitten 50 times (100 skip)
Now if you have a spare Knitten Kitten at lvl10 or more either you pay 50gems to hatch & deplete your food & pay remaining gems for feed if there is no luck during or close to 24hrs deadline.
Have a spare Knitten Kitten at lvl4 you need to worry about the timeline of 16hrs to evolve while at lvl10 & hopefully you have many food to feed it 50times & worse case is pay 50gems to hatch
Breeding a Knitten Kitten at 24 - 28 hrs deadline is almost as "be prepared" to spend gems, if you only have to rely on that 1 & only animal... the reason is not because you did not prepare the last step because
breeding 16, Hatching 16hrs, lvl4 evolve 16 hrs that is a total of 48hrs BEFORE the last step is unlock do remember even if you had 20hrs crop prepare & 2x 8hr prepare you need to spend gems to break this 48 hr deadline so you have to spend gems to speed up & a lot of food
Good luck everyone trying for cancer
