Sinus infections usually begin with the symptoms of a cold (for example, a runny nose, occasional cough and/or mild fever), and then develop into pain and pressure in the sinus cavities. About 7 to 10 days after initial cold-like symptoms other symptoms develop that suggest you may have a sinus infection.
The Ruins of Sescheron. The Ruins of Sescheron are available in the Adventure Mode of Diablo III. Specifically in Act III, near the Arreat Crater. They were released as part of patch 2.3. The area is designed to have a melancholy feel to it, with elements such as funerary art and pyres.
Portals in the Heretic's Abode. The Infernal Machine is an end game quest feature introduced into Diablo 3 in the v1.0.5 patch and changed in Patch 2.3. Prior to patch 2.3, the Keywardens would drop keys and the player would need one of each to craft one machine. Now, the Keywardens drop the machines directly. The Machines are used to open red portals to special dungeon areas where Ubers, super powered versions of certain quest bosses, must be defeated.
