There are no patch notes for this morning's patching (7-8AM Shard Maintenance), but it will take at lease 4 minutes for the patch to complete, depending on your computer's GHz speed and your internet connection.
The Rapid Raid event is near! Practice the Helm's Hold Dungeon during Dungeon Delves with any of your characters by completing the Skirmish!
One pointer for the Dungeon is that you will need at least one really good cleric or two clerics to keep up with the health. The enemies in Helm's Hold is similar to those in Mount Hotenow (level 50-60 region, with Level 60 region being Sharandar), which attack with fire. Strategize your counter attacks or you will end up tanking/taking more damage (loosing HP).
