Hello, I just started playing a few days ago and I've only really been confused about one thing so far. How long does it take for a sylesti to become an adult? I'm trying to breed two of mine and it's taking forever for my female to become an adult. Is there a way to make it go faster or increase it?

Assuming you're talking about your starter, starters and all pets made via the Generator using essences start life at 216 maturity hours- that is, the very start of adolescence.

sylesti aging is
72 maturity hours from newly created eggling to hatching; base time of 3 days, can reach 72 mh faster by 1mh per 6 nurtures recieved from players

144mh (72mh to 216mh) is spent in hatchling stage; base time 6 days, can reach 216mh faster at rate of 1mh per 4 nurtures (to balance the gain of +1 to lowest stat at rate of 1 per 8 nurtures

432mh is spent as an adolescent (216-648); base time 18 days, can reach 648mh faster by use of Magical Pies. A total of two pies can be used on a pet to skip 288 of the 432 hours, leaving a total of 144 (six days) of waiting. (Pies skip 144mh, and have a 72 hour cooldown)

(Found egglings, found hatchlings, and wild sylesti can be found at almost any mh stage, eg, wild syelsti can be caught and turn out to be adolescents with days left until adulthood, egglings can be found half-way through their growth)


On starters, generated pets, and pets that have been genetically tested you can see their exact age in maturity hours.
Take Aqua, have a look at her profile
"Age: 1 Day
Maturity: Adolescent (244/648)"

So we can see that at time of us writing this, she's 244mh old.
648 - 244 = 404
404 / 24 = 16.83
So she currently has a bit less than 17 days before she hits adulthood naturally.
