Now that shiny levels matters more in 9.2 and we have about 200+ shiny troops (haven’t counted, just my rough guess), it is time to introduce something similar to “event key” for shiny, to let people somehow concentrate their gaining of shiny tokens. So as title said, it’s good to let shiny dust convert to token for troop only from weekly kingdom. This way we don’t need to add a new item.
In case every shiny troop of weekly kingdom has reaches shiny level 3, there can be a pop up to tell player when he choose to convert shiny dust, and then nothing happens, or then convert to token for troops from other kingdoms. Either way is okay.
