Blizzard posted a very good and needed post of what will change on patch week and raid/season 4 week.
As an addition to our Visions of N’Zoth Content Update Notes, here’s an outline of what’s changing over the next three weeks, and when:
With scheduled maintenance on January 14:
- Artifact Knowledge will increase, bringing a player-character with a level 70 Heart of Azeroth to 17500 AP needed to reach 71.
- N’Zoth Assaults and Horrific Visions begin, and items from those activities can be Corrupted, but will never Warforge/Titanforge.
- Items from N’Zoth Assaults will scale with your character level, similar to other World Quests, and are already available at Season 4 item levels.
- Items from Horrific Visions improve as you complete additional objectives, going from item level 420 up to item level 470 from a full clear with 5 masks active.
- All Titan Residuum will be converted into Silver.
- Titan Residuum will not drop from any source for one week. This includes scrapping or disenchanting Seasonal gear.
- In competitive PvP, Season 3 is closed for titles and Seasonal rewards. The Notorious Gladiator’s Proto-Drake is no longer available, however, the Vicious War Basilisk mount can still be completed this week.
- Mythic Keystone dungeons are still playable using Season 3 affixes, and their associated rewards remain available through this week.
With scheduled maintenance on January 21:
- The new Ny’alotha raid opens for Normal and Heroic difficulties.
- Season 4 begins.
- Item levels increase by 30 for rewards from seasonal activities (dungeons, PvP, World Quests), and can now be corrupted by N’Zoth.
- Dungeon difficulty is increased for Heroic and Mythic difficulties.
- During this week, end-of-run rewards from Mythic Keystone dungeons and Rated PvP are capped at item level 445 (for Mythic +6 or PvP Rank 2).
- Mythic Keystone and PvP chests that are opened this week reflect Season 3 rewards earned the prior week, and cannot be Corrupted, but may Warforge/Titanforge.
- Item level improvements for weekly rewards now extend to Mythic +15, which awards an item level 475 piece of gear in the weekly chest to be opened on January 28 or later.
- The Darkshore Warfront now has a Heroic difficulty, with item level 460 gear rewards.
- Please note: Heroic difficulty will become available in the first Warfront that begins in each region after the Season 4 transition in that region.
- Any items not updated for Season 4 (for example, items from The Eternal Palace or Heroic difficulty Arathi Warfront) can continue to Warforge/Titanforge up to item level 455, but cannot be Corrupted.
- Titan Residuum is again available.
- All items that can be purchased with Titan Residuum, including new Season 4 items, have had their costs adjusted.
- A Mythic +10 weekly chest will award 1700 Titan Residuum, with each additional level awarding 90 more Titan Residuum. For example, a Mythic + 15 will award 2150 Titan Residuum.
- Specific item level 475 tokens cost 20,000 Titan Residuum. Random item level 475 tokens cost 4750 Titan Residuum.
With scheduled maintenance on January 28:
- Ny’alotha opens for Mythic difficulty and the first wing of Raid Finder difficulty.
- Mythic Keystone dungeons at +7 or higher, as well as PvP Rank 2 or higher, now award end-of-run items that scale up to item level 465 at Mythic +15 and Gladiator, respectively.
- Weekly chests for Mythic Keystone and PvP activities now contain Season 4 items, which are always Corrupted, and scale up to item level 475. Again, these items will never Warforge/Titanforge.
