Currently (from 2022.01.26 to 2022.02.23) there is an ongoing event in League of Legends: Wild Rift, called "Lunar Banquet", which makes it much much easier to earn enough Poro Energy for a Poro Store Random Skin Chest by giving Poro Energy for completing missions.
I unlocked nine League of Legends: Wild Rift skins skins so far. But unlocking League of Legends: Wild Rift skins (for free) is not easy. People usually pay for them. I have not spent a single cent on this game so far. And I am playing it for 428 days, so for more than a year.
I played 1982 matches so far, and I played 35 matches so far with Sona, with a win rate of 65.70%. Speaking of 1982, this Arcade skin is great tribute to the arcade video games of the 1980s.
Good luck and have fun.
