If you don't like grinding, farming, or playing excessive amounts in order to get items, then I suggest you do something with your life that does not involve gaming. Sports or hobbies seem to be popular choices.

To answer your Seraphynx question: the favored food for a sprite always gives it 1/4 of its heat bar, in essence, 5 of the favored items will level it up starting at 0 heat.

0* materials give almost no noticeable heat, 1* give almost no noticeable heat, same with 2* and 3*. At about the 4* level, materials start giving larger amounts of heat. At 5*, you can get some insane heat until about level 50, at which point you're better off giving the sprite its favored food.

If you have a bunch of spare 4* and 5* materials, consider feeding those to your sprite, or just craft a bunch of the favored foods to level it up. It's not cheap and it's not easy, but it's worth it in the end for Seraphynx.

rise or fall is pretty good for them anyway.

Stop replying to this thread. There's more than enough advice about "making crowns" in a bunch of other threads already, on youtube, and on other sites like steam.

Asking for "tips" on the game is good, but gathering information and taking notes on your findings will help and maybe will be a better approach.
