Ruins Of Sescheron
If you're going to use Kanai's Cube in Diablo 3's Season 20, your first order of business will be to go find it.
Inside the Ruins of Sescheron in Act 3 of Diablo 3, players could venture into the Immortal Throne Room, where spirits of long-dead Barbarians stood watch over the body of Chief Elder Kanai. Exploring this small corner of Sanctuary, players were told that the time was not yet right — there was nothing you could interact with and nothing to fight in the throne room.
Sescheron, the fallen.
After multiple attempts to get into a Torment VII game on the Diablo 3 Patch 2.3.0 PTR, I made a bet with myself -- if I start the game queue-in now, maybe I could raid through the entire X-hour queue and then finally the queue will pop when I'm done playing World of Warcraft with my guild.
Diablo 3 has been relatively quiet lately, relying on Seasonal play and new Legendary sets to keep players engaged.
