I'm kinda tired of all these threads. So here's all the information you need.
Just stop creating new threads.
Sett's Calling Card is going to reveal its secrets today as 7 PM GMT.
Sett release is likely going to be at 7 PM GMT too.
ARURF is going to be released alongside Mecha Kingdoms.
Mecha Kingdoms are released on 15th of January at 7PM GMT, as it was with all the locked ''milestones'' on the client.
Edit: Sett's calling card gives you Sett permanent. Thanks to guys in comments for information.
I'll keep bumping the thread to keep it somewhat pinned, at least until I go to sleep.
