I don't think something like this exists but it might.
Time travel scroll. They have different effects depending on the age. Baby dragons will instantly grow up but still have the same cooldown for breeding. Adult dragons will revert back to babies and reset their breeding cooldown. Basically, you can't breed them for a while after this scroll is used.
I do want some eternally youthful scrolls but the dragons I want to use them on grow up too fast for me to save up! So the time travel scroll would allow players to bring dragons back to baby age and then use the youthful scroll. Also makes you able to dress up your dragons as soon as possible!

@ScreamingAsexual - You can use Eternal Youth scrolls on any dragon, regardless of how old they are! A few of my Eternally Youthful dragons used to be adults before I saved up enough for their scrolls. The scroll automatically turns them back into a hatchling.

The Scroll of Maturity is 200g in the Gem MP, and it turns dragons (either regular babies or permababies) into adults. It keeps their breeding cooldown, so if you used a Scroll of Maturity on a 2-day-old Fae, you’d still have to wait 13 more days to breed it.

I think we already have these things.

Eternal Youth scrolls can be used on adult dragons to make them into babies (there's no time limit on when you use them) and Scrolls of Maturity can be used to make baby dragons into adults, either if you've used a Eternal Youth scroll or if you have the spare cash and simply can't wait five days.

I don't see the point in a consumable scroll that does the same thing as those.

Besides, they'd be available for gems anyway, not treasure, so I don't think anything would be easier for anyone with this item.

@greyjoy i did not know the scrolls reversed/advanced ages! Thanks for letting me know!
