One of the biggest changes to WoW Classic in the Season of Discovery is its level-gated content. In Phase One, players can get to Level 25, which will increase to 40, 50, and finally 60 in later Phases. At the end of each of these new brackets will be a new Raid, and for Phase One, the WoW SoD team has completely re-tuned the Blackfathom Deeps from a Dungeon into a 10-man Raid.
