With the sale of nemesis cell chests, many buyers will get some number of “extra” nemesis cells of types not desired. In particular, the base nemesis monster types are generally inferior in stats and skills to better non nemesis legendaries. Given the investment of the p2p players to get them, this recommendation is to allow some conversion of nemesis cells to elementium. The ratio could be adjusted to nearly value, 1 cell = 1 elemenium, 2 cells = 1 elementium, etc.
