The Elunes are basically your heroes in the game! You can get more by either summoning them, receiving them in the mailbox (when you start off as a new player), get them from events, Adventure stages and so on. They will come in different rarities, so I suggest that you start working on your best ones first! They can be Common, Uncommon, Rare, Epic and Legendary! The Legendary ones are the hardest to obtain, but also the best ones! One of the easiest ways that you can get Elunes is by going to the main interface and tap on "Summon"! There you will see a Premium Elune Summon, which you can perform once for free every 24 hours! This is a good reason to log in to the game, because you never know when lady luck might be on your side! Normally, a summon will cost thirt Rubies, but if you go for the eleven summons, you basically pay 300 Rubies! (one is free) I suggest that you save 300 Rubies for this, because it is super worth it if you want to try acquiring the best Legendary Elunes! Just save up the Rubies you get from completing the stages and other in game content (as I previously mentioned, the Rubies are super important). You can also do a Premium Ruby Summon if you are a premium player, but otherwise the normal free Rubies summon and the Friendship Summon is going to be enough! Now for the Friendship summon, this comes completely for free, but you will need to have in game friends! They will send you Friendship Points (the hearts) with which you can summon!
