So received an email from Blizzard and you can see the Vessel of Hatred via the Bnet launcher.
If you visit vases of hatred (dot ) com
accept cookies if you want
enter zip code of your Foe (NEXT)
play with the evil scale (NEXT)
you’ll see a poem/haiku of sorts and then you’ll see two circles. One has a Horse (little lady?) that says “In-Game Reward”
from there you enter your battle net tag + your email address.
The bottom of the next card/window says …
*IN-GAME REWARDS BEGIN DISTRIBUTION TO PLAYERS ON NOVEMBER 4th
*INACCURATE ACCOUNT INFO WILL RESULT IN INELIGIBILITY
