How about making Aurora Heart into mix elements or not just fire plz.
FORUMAs pics below.

Been playing since the game start last year, still having issue with fire evolve materials lacking. As someone who have more than 100 6 stars child is still struggling, not to mention those newbies. I know we can lvl up different 4 stars child to lvl40 to replace evolving Aurora heart, but there are way too much place need stamina now, Ghost parade and keep coming Narrative dungeon are big and constant cost; and you still need to spare some to lvl up new child. Old story, new mention.
You might wanna adjust your playstyle acording to the ressources available to you...
Nevertheless, I support your request for different element Aurora Hearts.Must admit that currently kinda lazy to lvl different elements 4 star child to lvl 40 to replace Aurora heart lol.
We have asked this request several times, just to remind the develop team what ppl really want.
I used to directly use 5 star child to evolve, but now need to spare them into rebirth=\, and feeling more lacking fire evolve.Using stamina on narrative seems to be a good idea atm anyways.
Also, I am super jealous of your crystals ;PWith that many crystals and stamina, did you ever consider leveling up three 4*/3* childs to lvl60 6* for Metamorphosis in HoR?
It works, but not efficient I guess, takes thousands stamina and millions gold just to get one.
that would be awesome. I have so many Auroras that needs to be evolved...I have also been playing the game for a year. I usually buy ruby from rumble shop but I wish they would add the 1 star and 2 stars rocks as well...
ikr I got all element Crystal's and yet I'm ALWAYS short on evolving my fire units
you can evolve 4 stars to 5 stars as the materials of evolving 5 to 6, that will balance the resources
I do, but it takes time and staminas.
As you mention, I also bought all the full lvl exp 4 stars slime from BG store with this discount.
