08/01/2016 Edit: The level caps have now been reduced in line with the current den requirements for the respective dragons (Sobek and Droyeuse).
Let’s face it, the last few events have taken their toll and the last thing you want to do is figure out whether all that work was worthwhile or not.
Here are the details:
Droyeuse is breedable with around 69,000 tokens. From all reports, you also get Elixis when you breed him.
If you are level 63 but less than 70
You should be able to breed him in your incubator if it is high enough level. If you are lower level than this, be thankful of Sobek as he seems to be shaping up to be a decent enough dragon.
At around level 63 you will be on your way to breeding gold dragons, if you haven’t already. That means that you will most probably have a few green legendary dragons and Amarok/Durga.
Amarok will be capped at level 24, which means he will have attack power of 73k and health of 791k
If you breed Droyeuse, he will have a starting attack power of 70k and health of 760k, which will be capped until you reach den 16.
This means that by blowing your tokens at level 63, you will end up with 60,000 tokens used on a dragon that is actually worse than Amarok (since Amarok has two resists, explosive shield and cure poison at this time).
If you are level 70+
If you are level 70 you are still going to want to consider if you want Droyeuse or not. By this time you will be well into breeding gold dragons, so by taking 60k tokens out of your pool you will be removing your progress towards any of the other gold dragons like Whalegnawer and Consurgens. At level 70, he only has access to Intimidating Roar, which his breeding buddy Sobek also has. There’s obviously a bit of difference in health/attack when comparing Sobek and Droyeuse at this time, but when you add 60k tokens into the mix you can easily start to regret your move.
If you also consider that with 50k tokens you can get both Yersinu and Bander, you probably start kicking yourself hard.
Don’t get Droyeuse unless you have nothing better to spend your tokens on. Since the den caps are higher than all other dragons in the game, it’s a complete waste of time waiting for him to reach the dizzy heights of the other legendary dragons.
