Energy required to grow
The energy required to grow is linear, doubling each time. In the formula, the x 4 represents the sub-upgrades. Each level requires four upgrades to be completed before moving up to the next level. The strategy for upgrading depends on several factors, including how much space you have, how many habitats you can have, and the maximum coins available for a given habitat. Upgrading to a high level dragon is good, but if the habitat max coins is low, you should not buy into it if you do not play often. Low max coins values are good for people who play constantly (on phones or people who stay home all day). High max coins are good for people who only play for one period per day (like at night, after school or work).
