First day of public testing. PTR was online for almost three hours.
Ruby Sanctum contains couple of trash packs, three (emblem-droping) adds (like sartharions lair) and the boss Halion.
what you can see in the vid:

1) Baltharus the Warborn - fight
2) Saviana Ragefire - fight
3) General Zarithrian - fight

4) Halion spawning (no fight, you can see this in another video of mine, just check my profile)
