Talk:Prime Millennium Light Soulstone/@comment-116.50.199.236-20170601104950

Why this card active skill is the same with millennium light soulstone? while other attribute prime soulstones active skill has the upgraded version of their previous version (example:  millennium light soulstone,  millennium pyro soulstone,  millennium shadow soulstone,  millennium aqua soulstone,  millennium terra soulstone )

I just want to know if is really created that way or is just a mistake.
