In WoW Season of Discovery, the initial Phase is packed with fresh secrets, abilities, and various alterations and activities for players to explore and experiment in the realm of Classic Azeroth.
Although it's been less than two weeks since launch, enthusiastic players who have already reached the current level cap of 25 are eager to learn about the release date for the next level band, 25-40. Season of Discovery will have four Phases in total. The year has 12 months, and if we divide that by four, you can expect a fresh Phase every three months. While Blizzard has not revealed the release date, we estimate that Phase 2 will likely come out in February 2024.
Phase 2 will introduce new raids (including Gnomeregan Raid), PvP events, dungeons, and other additions, offering fresh challenges and opportunities for players to explore and conquer.
Here Are Some New Features and Content:
Level Cap Increase
The maximum level cap will be raised from 25 to 40. This increase allows players to reach the 41-point talent tier, opening up new possibilities for character development and strategy.
A Max-level Gnomeregan Raid
Gnomeregan, as a 10-player raid, offers new challenges with revised boss mechanics and encounters.
Expected bosses include 
Grubbis, Viscous Fallout, 
Electrocutioner 6000, 
Crowd Pummeler 9-60, Dark Iron Ambassador (Rare), and Mekgineer Thermaplugg, each with potential enhancements, unique abilities, and loot, suitable for raid-level gameplay.
This raid offers cutting-edge challenges and loot for max-level players. Rewards are expected to include traditional raid gear (weapons, armor, and accessories), improved quest rewards from the existing Gnomeregan questline, unique cosmetics like mounts and transmog sets, possibly new Runes expanding cross-class abilities, professional materials, and wealth rewards in the form of WoW Season of Discovery gold.
New Leveling Zones (Level 25-40)
Players can explore large areas like Arathi Highlands, Thousand Needles, Desolace, and Stranglethorn Vale, each offering hundreds of quests that continue the classic storylines across these vibrant landscapes.
Stranglethorn Vale PvP Zone
This area becomes the new contested PvP zone hotspot for world PvP, with special rare loot, titles, and other rewards to incentivize participation in open-world PvP.
Increased PvP Ranks
The rank cap will be raised from 3 to a speculated 9 at the start of Phase 2, providing stronger PvP gear for organized battles.
Potential Catch-Up Dungeons
New 5-man instances, such as Dire Maul or Blackrock Depths, offer alternative paths for gearing up alts or players who are behind on progression.
New Quests
In addition to the new quests added in Phase 1 with the Runes, players can expect even more quests in Phase 2.
Rune Engraving Mechanic
A new Rune Engraving mechanic is unlocked from Discoveries, enabling new roles for certain classes. Phase 2 will add more runes and abilities for each class and spec.
Here Are Some Tips to Prepare for SoD Phase 2:
Level up to 25 and gear up with the best items you can find or craft. You can also use consumables, such as potions, elixirs, flasks, and food, to boost your stats and performance.
Learn the mechanics and strategies of each boss and trash mob. You can use guides, videos, or addons to help you with this. You will also need to communicate and coordinate with your group and assign roles and responsibilities.
Stock up on any items or resources that you might need during the raid, such as repair kits, reagents, bandages, and water. You can also bring some extra items to trade or share with your group, such as keys, scrolls, or runes.
Have fun and enjoy the challenge. The raid is designed to be a rewarding and engaging experience. You can also earn some loot and reputation from the raid, as well as complete some quests and achievements. Now, in the first phase, you can quickly reach the max level of 25 by using WoW SoD boost service.
