Hi, someone know when Elementalist Lux came out?

We don't know. Some theorize that the last part of the star-guardian page will actually be a teaser for elementalist lux(like star guardian lux getting some sort of power-up turning her temporarily into elementalist lux or something like that)

In the end it is even possible that the leaker is a troll and made that last part up just to mess with us.

I think they will reveal or tease at Worlds. It would be pretty epic.

Not anytime soon.

Probably next patch cycle? Cause thats how these things usually go when you see these types of leaks, specially since the past leaks released with Elementalist Lux were released at the same time...and rather than push it in the patch where you have the release of Ivern and the Legendary skin of Star Guardian Lux, they would release it in the next patch cycle after that, but being teased in this current one.

And if it does end up having connections with the Star Guardian lines ("not saying it will, just a guess"), then the potential part 4 of the SG story maybe used to tease the new Ultimate skin. It would be a different way of teasing a new Ultimate skin than in the past, as it is the custom with all these Ultimate skins (doing something different each time).

Soon™
