The Scales of Knowledge being only in the final dungeons for each world is really inconvenient, given that each world's final boss is only one of dozens in each world that can drop spellements. Often times farming the final world bosses is more of a hassle compared to other bosses. It's also a hassle having to constantly run back to the final dungeon to use the scales of knowledge then run back to where you were farming every 2 hours.
So I propose that level scaling elixirs be purchasable from the crowns shop with a gold option included. Instead of each level scale being it's own elixir in the shop, there would be a single elixir for purchase, and after selecting it, you would be presented with an interface asking what level you would like to scale to. Each level would only be purchasable after completing the final quest in the questline of each world and defeating it's respective final world boss.[Krokopatra>lvl 20|Meowiarty>lvl 30|Jade Oni>lvl 40]
