Hi everyone, thank for the effort of reading and responding to my question.
Would it be worth it to just fill my inventory with 1-key rewards to fill out my sticker book if I don't necesarily need any special monster sets right now?
I ask this because i don't really know how the sticker book works, i get that i can craft these items later again. But it it character bound?
In my head it's pretty obvious but i just want to make sure that i'm thinking correctly about this.
