WoW MoP Classic Phase 3 Preview | Isle Of Thunder, Throne Of Thunder Raid, And Major PTR Updates
Posted: Nov 04, 2025 Views: 52
Phase 3 of WoW MoP Classic seems to be just around the corner. The official announcement includes two PTR tests, and they've also released Mists of Pandaria Patch 5.5.3 PTR developer log.
The developer log reveals most of the content players are interested in, including how to unlock new zones, world bosses, and the much-anticipated Thunderforging system.

New Zones
The new Phase 3 zone, the Isle of Thunder, will be unlocked similarly to Sunwell in The Burning Crusade or Ahn'Qiraj war effort in WoW Classic. Players will need to complete daily quests, unlock additional questlines, and find rare elites and treasures to gradually unlock this zone.
World Bosses
Oondasta is located at the northernmost point of the Isle of Giants, and players can test it with the developers on November 7th at 3 PM.
Another World Boss, Nalak, is equivalent to Sha of Anger in Phase 3, dropping Class Tier Sets and current PvP season gear. However, Nalak will only appear after Thunder Isle is fully unlocked, making it part of the final phase.
Throne Of Thunder Raid
Throne of Thunder contains 12 unique boss fights. Its PTR testing period is as follows:
- Round 1: November 4th, 10:00 AM PST to November 7th, 8:00 AM PST.
 - Round 2: November 14th, 10:00 AM PST to November 17th, 8:00 AM PST.
 
Mogu Runes Of Fate
Phase 3 will introduce Mogu Runes of Fate, which are used for bonus rolls in Throne of Thunder raids, Nalak, and Oondasta. There is a weekly cap on how many Mogu Runes you can obtain, similar to Elder Charms of Good Fortune, with each Mogu Run costing 50 Lesser Charms of Good Fortune.
Thunderforging System Changes
Thunderforging system was quite controversial in the original Mists of Pandaria. Initially, Thunderforging system gave equipment dropped from Throne of Thunder (Normal or Heroic difficulty) or obtained through extra dice rolls a chance to become Thunderforged items, gaining an additional 6 Item Levels.
The system was entirely based on RNG, which made gear acquisition highly reliant on luck, easily leading to conflicts between players over loot. Therefore, the developers made some changes in WoW MoP Classic.
The developers decided to allow players to use Justice Points to upgrade non-Thunderforging Throne of Thunder gear twice, each time increasing the item level by 3, for a total increase of 6 item levels, while Thunderforged gear can no longer be upgraded.
This change also reduced the randomness, lessening the frustration of Thunderforging gear drops, while still making bonus rolls and non-Thunderforging gear valuable. Additionally, Thunderforged gear saves Justice Points needed for upgrades, so it remains valuable, but won't cause excessive competition due to its overwhelmingly powerful stats.
Overall, the overall item level of the raid will be higher than in the original phase, slightly reducing the difficulty of raids. However, given that Thunderforging raids are significantly more difficult than T14 (such as Mogu'shan Vaults), this change is reasonable and beneficial in WoW MoP Classic.
Finally, the number of attempts to challenge Ra-den - the hidden final boss of Throne of Thunder (Heroic difficulty only) - is limited. Raids must defeat him within 30 attempts, or he will disappear, and players will have to wait until the following week.
Challenge Modes And Rewards
Phase 3 Challenge Modes now include Platinum Medals, requiring players to complete dungeons within a set time to earn additional rewards.
Each dungeon's Platinum Medals rewards an achievement and a dungeon-exclusive toy. These toys are Platinum versions of existing items and are count-wide. The following are the toy items offered in each dungeon:
Temple of the Jade Serpent: Platinum Boots of Expeditious Retreat
- Stormstout Brewery: Platinum "Little Ale"
 - Gate of the Setting Sun: Platinum Rod of Ambershaping
 - Shado-Pan Monastery: Platinum Potion of Invisibility
 - Siege of Niuzao Temple: Platinum Amber
 - Mogu'shan Palace: Platinum Battle Horn
 - Scholomance: Platinum VIal of Polyformic Acid
 - Scarlet Halls: Platinum Battle Banner
 - Scarlet Monastery: Platinum Sacrificial Dagger
 
Note that the opening hours for each dungeon vary. It's best to check their opening times before attempting a challenge:
- Temple of the Jade Serpent: 10:15
 - Stormstout Brewery: 8:15
 - Gate of the Setting Sun: 8:00
 - Shado-Pan Monastery: 14:00
 - Siege of Niuzao Temple: 12:15
 - Mogu'shan Palace: 8:15
 - Scholomance: 10:15
 - Scarlet Halls: 8:00
 - Scarlet Monastery: 9:00
 
Additionally, completing all Challenge Mode Platinum ratings in Seasons 2 and 3 will earn you the server's first achievement.
First-time Platinum Challenge completions for each dungeon reward you with Platinum Coins, which can be exchanged for transmogrification sets, toys, and mounts.
Furthermore, Celestials bosses will be updated, and their loot and mechanics may include equipment and boss abilities from the Throne of Thunder.
At the end of each Challenge Mode season, the player who maintains Realm Best Time will receive an exclusive title and mount:
Season 1
- Title: The Mistwalker
 - Mount: Reins of the Celestial Serpent
 
Season 2
- Title: Mistborne
 - Mount: Reins of the Celestial Tiger
 
Season 3
- Title: Heir to the Mist
 - Mount: (Not yet announced)
 
Other Updates
After reaching Exalted reputation with The Tillers, players can speak with Farmer Yoon to take over Sunsong Farm (requires unlocking 16 farms).
Warlocks can start a questline through Codex of Xerrath; completing the quest changes their fire skill's effect to fel green.
This concludes the general content of Mists of Pandaria Classic Phase 3 PTR. Although the official release date hasn't been announced yet, it's clear it won't be too far after PTR ends. It's expected to go live around early December, though no exact date has been announced yet.
