1% rate is kinda fine if you can give it a try after grinding for 1 hour or so. But probably you will need to grind 12h day to have 1~2 chances a week while they will put some boxes in Item Mall with them in it
Of course, we've heard it - you can drop these relics with 0.1% chance from the Item Mall's Anniversary Special Box (Gold)! That supposed to be irony, though I'm almost sure it'll become a reality. Let me start this: Xd
Is the lvl of a character in comparison to a mob lvl gonna affect the drop rate of the collection items? Or is it just like the rudolph event where it doesnt matter which lvl you are, it's always 100% or any other fixed drop rate percentage?
