Scratch

When you select Scratch you will be brought to this page. The text above the Scratch selections will have stuff about the current scratches, the rares, and whatnot. And if there's any events for certain draws.

Friend Scratch - To perform a friend scratch you will need friend points. To scratch 1 you need 200 friend points. To scratch all 9 (the whole card) you need 1800 friend points. The units you tend to get from this are 1☆-3☆ in rarity. For obvious reasons it's harder to find rare units in this scratch.

Rare Scratch - To perform a rare scratch you will need Chips. To scratch 1 you will need 5 Chips. To scratch the whole board (9 squares) you need 45 Chips. You tend to get 3☆-5☆ units from these scratches.

Coming Soon - Limited Scratch. These are for limited events, usually collaboration events, like the recent Attack on Titan collaboration scratch. Currently, all of the Limited Scratches cost 5 Chips per scratch.
