  • Using economic analysis I found that the Double Rainbow Dragon Scenario had a daily ROR of 14.10 over 30 days while the 3 Solar Eclipse Dragon Scenario had a daily ROR of 26.50.

    The NPV10 of the Double Rainbow Dragon Scenario was 3.5M while the NPV10 of the Solar Eclipse Dragon Scenario was 7.5M.  

    Just though I'd share for anyone on the fence about what cash flow scheme to use in Dragon Vale.

    • I like posts like this! Thanks...

      Having said that, not using Kairos will make the two Double Rainbow Dragons "earn" back the difference in investment in about 45 days:

      ((10,000,000 – 5,000,000) / (998 – 921)) / (60 * 24) = 45.1

      Kairos will knock some four days off from this total. I intend to play longer than until the beginning of 2014. So I should go for the Double Rainbows.

      Is my thinking flawed, or are we discussing two different things here? (I used to be a Math major and never really got to understand Economics...)

    • I'm an engineer so take what I say with a grain of salt... but:

      My analysis asks the question: "If a player has 10,0000,000 coin how should he invest it? Should he buy 1 large rainbow habitat that will earn him a daily ROR (Rate of Return) of 14.10% or 2 large sun habitats that will earn him a daily ROR (Rate of Return) of 26.50% each."



      If this were a set of investment opportunities in the "real world," incremental economic analysis would suggest that the Solar Eclipse Dragon Scenario is the way to go.  

      The question I'll ask you is: Why spin your wheels for 45.1 days trying to make up the difference when you could be making more money with large sun habitats?

    • But...: in Dragonvale Habitats are a more scarce 'commodity' than money - Dragon Cash - is.

      Taking this into account, wouldn't the Double Rainbow solution remain 14.1%, whereas the Solar Eclipses be reduced to 50% of the 26.5% you mention? (Which is what I intuitively believed: Double Rainbows are better, but only marginally so...)

    • I would rather have maxed out habitats with Solar and use the spare money to buy treats. Thus leveling my park faster. 

      Even if you drag the equations out to a year, the Solar is going to give you a better Net Present Value and Rate of Return. 

      As far as the game goes the difference is almost negligible. The advantage is getting damn near the same cashflow from half the upfront habitat cost. 



      Using this strategy to pick Solar over DDRB would probably benefit the "park grower" "start up" player better than someone who is already established.

    • I think there is a small difference (in favor of the Rainbow solution) of 2.6 billion DC for an entire year (58 Habitats, entirely dedicated to either Double Rainbows or Solar Eclipses, including Kairos). The difference in the purchase price for both Habitats becomes negligible (only a quarter of a billion DC after all...). And while this may interfer with the NPV or ROR, I'll take the cash any day!

      I guess, however, that this is quite academic and that any player, new or experienced, will be more influenced by the order in which he gets his Epics than by any real economic, mathematical or other rationale...

      ok...

      which basic element is best to invest in. if i try getting all the dragons of an element what should it be

    • What is your goal? To make as much money as possible? I wouldn't use anything but Epics for that. Not because they make more money (per Habitat per hour), but because their Habitats can store more cash and you don't have to get up a few times in the middle of the night to collect the cash before the Habitats is filled up and you lose the rest...

      If you don't have any Epics yet: just keep on breeding, it will happen eventually!

    • As for the calculation (for that’s the part you selected as a quote):

      All earnings for Dragons are given per minute. The number of minutes in a year can be calculated thus:

      60 x 24 x 365 = 525,600

      Kairos increases this by six hours every 96 hours (= four days) = 1.0625

      Total number of ‘counting’ minutes becomes

      1.0625 x 525,600 = 558,450

      There is currently a maximum of 58 Habitats allowed (not counting the Reward ones, but they can’t be ‘exchanged’ for a different one, so that is irrelevant). This means that, for all 58 Habitats, there are

      58 x 558,450 = 32,390,100 minutes we are dealing with.

      The difference per minute for the Double Rainbow solution vs. the Solar Eclipse solution is 77 DC per minute. Or, for the entire year and all 58 Habitats this comes to

      77 x 32,390,100 = 2,494,037,700 of Dragon Cash.

    • If you want to use a hybrid for this you can use a cotton dragon at level 20 with four posiive boosts will give you 448 a minute but its habitats cannot keep high levels of dragon cash.

    • Yep, for Hybrids Cotton is the best earner. With boosts.

      With the Large Seasonal Habitat's introduction recently, the best way to earn Cash isn't Large Rainbow Habitats with two Double Rainbow Dragons anymore. Having four Seasonal Dragons in a Large Seasonal Habitat will earn you about 23% more per Habitat. Which is quite significant of course. It will take you a bit of time to get the required 240 Seasonal Dragons though. But if you're going for levelling up all your non-Epics to level 20, 'time' isn't something that scares you.

      Yep, my crowned cotton gets me 447 cash per minute with 4 boosts.

      But I still dislike this thread, as it insults me. To be called worse than a solar eclipse....

    • Interesting thread, I can see people spent a lot of arranging their parks to get the most DC. My only question is... Why? The only currency in short supply and might have to be raised is gems. From day one I ignored my DC as there were always plenty to purchase whatever I needed. I only played with the goal of getting all the dragons (Still Missing 3). After 1 year I'm lvl 51 with 3.5 trillion DC.

    • I convert DC into Treats that I use to level up my Dragons. I started playing before the Shrines changed into decorations. Having Golden Shrines used to require a lot of Treats. And even today --- unless you want to spend a large number of Gems, that is.

      But I agree: if you don't care about whether your Shrines are Golden or your Dragons are all leveled up to their max, trying to get the most DC the fastest would be of little interest to you.

    • Now, with the option of having a gemstone habitat, we can earn more gems than ever. Anyone want to do an analysis of gem acumulation if we replaced all possible habitats (for me, 60) with gemstone habitats and each was fully occupied with 2 level 10 gemstone dragons? Although a decent mathmatician, it would take me awhile to ferret out the process on this one...especially if I had to account for the cost of the 59 habitat investment (at a whopping 150 gems each), plus the dragontreat cost to get all the dragons to level 10. Still, I'm starting to breed for tons of gemstone dragons, just to see if it can be done in a lifetime. . . I'm sure Backflip will find a way to throw in a monkeywrench.

    • I’m not sure I understand your question correctly. I think you’re asking how long it would take to earn back the Gem investment required to purchase the 60 Gem Habitats. But would that include the time it takes to breed the Gem Dragons? I don’t suppose you’ve already stored some 140 Gem Dragons in your Habitat…

      But the straightforward, basic question: how long does it take to earn back a Gem Habitat is pretty simple: 75 weeks. Multiplying the number of Gem Habitats by 60 doesn’t change this: it will still take ‘only‘ 75 weeks to earn back this investment.

      For the record: this does ignore Kairos.

      But if you intended your question differently, please elaborate a bit. I do like puzzles like this even if I don’t think I will want to be spending the next three years breeding nothing but Gem Dragons (assuming it takes about a week, on average, to breed a single one).

    • These calculations always assume that you are playing the game constantly and you never let a habitat max out. I have lightning habitats that earn ~500 dc/minute so they max out in 100 minutes. I sleep at night and have some semblance of a life so I am not playing the game every 90 minutes 24 hours a day 7 days a week.

      Also I highly doubt that the claim by one of the posters above about having 3.5 trillion DC is quite correct. 3.5 billion I can see but trillion? Not gonna happen.

      60 parks * 2 DR dragons * 499 DC/min * 60 min * 24 hrs * 365 days = 31,472,928,000 DC

      At that rate it would take 111 years to get to 3.5 trillion DC. Kairos might knock it down to ~100 years....

    • The original post is about comparing Solar Eclipses and Double Rainbows. Both reside in Habitats that let you live the semblance of a normal life without having to worry about maxing out the Habitats: twice a day harvesting suffices.

      And as far as Kairos' effect goes: it's a little better than six percent, so it would knock it down to about 105 years. Which doesn't diminish the value of your calculations and is only added in honor of the gods of mathematics.

    • Can anyone crunch the numbers for this with the Dusk Dragon instead of the solar eclipse dragon? The Dusk Dragon now has the highest earning rate of all the sun/moon dragons. A sun/moon habitat filled with dusk dragons can now make slightly more DC than a filled double dragon habitat. 

      Also why solar eclipse dragon? The Blue moon, lunar eclipse, and solstice dragon all have the same earning rates. If you're also talking about breeding times, the solstice dragon is much lower than the solar eclipse. Again, another perk for the Dusk Dragon is that it only has a 20/16 hour breeding time and a 30 second incubating time. If you're going to be grinding for dragons Dusk dragon is the way to go.

    • I noticed this (Dusk Dragon's earning rate) too. But I was going to wait to see what happened with the Celestial Habitat after the event. It will make a big difference if it is a one-off thing, or if it's going to be for sale in the Market.

      And I guess the original poster likes Solar Eclipses over the other ones. There is no difference between them, as you point out.

    • Basically... I don't play DragonVale economic style... and is anybody know how to make a good park that each island has 1 dragon boost and on that dragon boost's type is same with every dragon on that island's primary type. Example: metal, brass, and malachite dragon with metal dragon boost on one island, while another one has dark, mirage, and root? or fungus is dark/plant? I think root is dark/plant.
