DRAGONFLIGHT SEASON 2
MYTHIC+
There are new affixes and adjusted affixes available for testing. Players can purchase scrolls from the keystone vendor to add to these to their keystone.
New Affix: Incorporeal – While in combat, incorporeal beings appear and attempt to destabilize players with spells that reduce their damage and healing done. Incorporeal beings are susceptible to all forms of crowd control.
New Affix: Afflicted – While in combat, Afflicted Souls appear that seek the aid of players. Afflicted Souls spawn with poison, curse, and disease afflictions.

Updated Affix: Explosive – Fewer Explosive Orbs spawn, but they now have substantially higher health.
