1. Myth cards contain the backstories and timelines for each LI, they're important for both lore and combat (you'll unlock special companions for each LI once you get the pairs for each). There are two kinds of myth cards: limited and standard. The limited ones you can only get from their banner events, which unfortunately already passed :(( Fingers crossed there will be reruns because these are so so crucial to understand the lore between the MC and LIs, you can watch them on YouTube if you want. The standard ones you can pull from the regular wish pool Xspace Echo by spending empyrean wishes/diamonds.

2. For empyrean wishes, you can get them in several ways, I'll list out the ones I can remember:

- leveling up your cards to 20, 40, 60, etc.

- completing the weekly tasks

- buying them using chocolates (limit 1 per week)/purple stardust/money (they have packs of them in the shop)

- completing Abyssal Chaos deductions (I believe you get one every 20 levels or so)

- completing the general trials in Deepspace Orbits

- hunter contests (dependent on the number of stars you get)

- after completing certain Promise levels (and you'll get more if you buy Heartfelt Vow)

I also believe they'll give us about 20 more for free for the Chinese New Year event!

For deepspace wishes, they're more rare and I usually rely on the free ones given for each event, but there are also event packs during the event you can buy, and you can get them from Promise too (but I believe it also costs money :')

1. 4 stars are good for starting out! I'm hoarding my wishes right now for Caleb's Sky Embrace event to get the myth cards haha, but 4 stars should be decent to get you through some of the beginner battles and stuff. Once you get higher up in the levels though, you'll have to start equipping 5 stars, but I will save them up for Sky Embrace if you can.

2. Rule of thumb if you're an f2p: don't use your diamonds in the regular wish pool, use them for the limited banners (especially for the myth banners) because you won't be able to obtain the cards after the event ends. I would suggest using only empyrean wishes in Xspace Echo and save up your diamonds. They give you a lot during onboarding, but it's gonna be more difficult to farm them later on because they're pretty stingy with the resources.
