Currently, there are 4 habitats on the Gem Dragon island, and each can hold multiple gem dragons. I finally have more than 4 gem dragons, so now I have to decide how to arrange them. What is the best arrangement to earn max gems? I'm particularly interested in avoiding gem loss by leaving them for too long. They have such a long timer I often forget to check them in a timely manner.
All the Gem dragons thus far (except the Jade dragon, which has as slightly slower timer) have the exact same timer and all the habitats have the exact same storage capacity. The only optimal pattern is to make sure as few dragons are in each habitat as possible; instead of keeping 3 in one and 1 in all others, put 2 in each habitat, for example. If you have Jade dragons, space them out evenly (or, more likely, keep a single one) to minimize their impact on your gem earning rate.
At level 10 each dragon will give one gem every week (always level these dragons to 10 first! they have by far the most to gain from your food). Each habitat will hold three gems.
I found that the gemstone timer is not on the dragons themselves, but on the habitat. I had 1to dragon in two seperate habitats (turquoise and peridot) for two hours after collecting my weekly gems, and when moved into the other two habitats on gemstone island, the timers reset to 7the days. But when put back into either of the two original habitats, the timer loses the 2 hours. Also, 2 gemstone dragons in a new 7 day time habitat (ie: the habitats that have never held a gemstone dragon yet) make it 4 days to collect, but im not sure if i get 2 gems in 4 daus or just one. Ill let you know .....in 4 days lol.
I checked and only received 1gem from two in the same habitat. The timer doesn't follow the dragons,I have 4 now (opal, peridot, turquoise, emerald) and one habitat has a 3 day timer with one dragon in it, a 30 hr timer with 2, and a 25 hour timer with three. so I'm keeping two per habitat, it makes the most significant upgrade per dragon (4 days not 7) whereas a normal 7 day timer with 3 dragons makes it 3 days and some change. What you can do is get your gem early by switching from 2 to 3 dragons when there are only hours left on the timer. then once the gem is collected move back to having 2per habitat. So you can't receive one gem per dragon but you can get one gem per habitat and with 2 dragons in all four habitats you can get 4 gems in 4 days and depending on when you place the dragons in the habitats, you can set it up where your getting 1 gem per day.
