They’re here! Here’s one place you can purchase them – in the Collection screen for a particular champ – but you can also purchase them in the Shop. You can unlock them for one champ at a time, or you can purchase a passes to unlock the Basic or champion-specific Eternals for ALL champions – current as well as all future champs – which seems like the way to go, if you like the whole concept.
Anyway, I decided to test the waters by unlocking the ones for Xayah, then I went ahead and played a match. There are some pretty neat callouts that pop up during the match now – it’s hard to say whether they’re Eternal specific, because you can’t see the enemy Eternals, and no one else on my team had them unlocked. Although we lost the match after quite a battle, I earned an S+ for the match:
At the right side of the end-of-match screen, your progress towards each Eternal is shown. I didn’t realize it scrolled, so I didn’t capture the whole screen, unfortunately. Here’s what Xayah’s mastery page looks like after the match:
All in all, I’m giving the system a thumbs-up. Although not free, the basic Eternals can be unlocked with BE, and the passes are quite a bargain, assuming you play a decent variety of champs. I’m going to go ahead and buy the passes the next time I spring for more RP
