  • The Arachnid Quarter – A web choked maze filled with many-legged minions.
  • The Plague Quarter – Necromancers brew deadly plagues while a fungal monstrosity lies in wait.
  • The Military Quarter – Tireless undead knights perfect their deadly arts within these chambers.

iPad Performance Improvements

Quote from Sapperwix

Greetings All,
With Patch 1.1 we have made a number of improvements to how the Hearthstone iPad client handles memory and performance. Mini 1st Gen and iPad 2 users will see the most marked improvement as this should resolve many of the crashes some of you were seeing, especially around transitions.

That said, I would still encourage you to continue using best practices:
Limit the amount of apps running in the backgroundKeep at least some space available on the hard driveRestart the client if you're seeing drops in performance
Restart the device If you're consistently having major issuesWe are consistently continuing to improve the mobile Hearthstone experience. I continue to welcome your feedback and appreciate your patience.
