How do you get a sylesti to max stats? I have no idea after coming back with the new changes and have wasted all my elixirs on bosses ;;
Also how much would their price be? (If you have one or more to sell I'd love to buy ;) )

You breed them for generations, using Prismatic Philters or other such stat boosters on the eggs, and the stats go up little by little. :) From what I've seen they go for about 300k, but I've seen much higher, and a few closer to 150k at times. :)

Ooh that's a lot of work '^^ Thank you so much Hakura! :) (Time to save up for buying)

And expensive! No problem, glad to help. :) (Good luck! With the event you should get enough in no time.)

If you want cheaper ones I would keep on eye on Upsidedownsarah's puffadores~ She sells them 50-100k usually ^^

Ahh okay! X3 Thank you!~ <3

Just as something else to help you out, here is a max stat directory where you can see a list of many of the available max stat pets and who sells them and for how much.

Max Stat Directory

EDIT: It does look like someone may have messed the spreadsheet up though, so if you go to the December 26th version, you'll be able to see everything.

Ohh that's a wonderful guide! Thank you so much! :D
