Emalon the Storm Watcher is also available to be tested in the Vault of Archavon depending on PTR Wintergrasp status. Test Patchwerks will also be available on Wednesday.
For Hard Mode testing, Shirts of Uber will be available on Ursula McWeaksauce to help simulate a raid having obtained Ulduar gear. Check the entrance area of Ulduar for the vendor.
A new Build 9722 has been deployed on the PTR too, posts on World of Raids and MMO Champion.
There are a few important changes for every raider :
All flasks recipes will now create 2 flasks for the same amount of ingredients but now last 1 hour instead of 2.
You can fish a Sea Turtle Mount from Northrend fishing pools.
Undying/Immortal & Ulduar equivalent achievements, (source):
First, Naxx achievements are going to stay, no drakes anymore but the titles will be kept. And now, the Ulduar equivalent will be out of the meta (for the drakes) and will give a different title, and can be done in several resets (not necessarily in the same week as for Nax).
For Paladins :
Glyph of Seal of Blood -- When your Seal of Blood, Seal of the Martyr, Judgement of Blood, or Judgement of the Martyr deals damage to you, you gain 11% of the damage done as mana. (Old - Glyph of Seal of Blood -- Your Seal of Blood or Seal of the Martyr increases the mana received from Spiritual Attunement by 10% while active.)
Though this is much better than the, now outdated, earlier version of this glyph. It is sad that all Retribution Paladins have to spend a major glyph to compensate for the loss of Spiritual Attunement with absolutely no dps gain.
Judgements of the Wise now immediately grant you 25% of your base mana. (Up from 15%)
This was really necessary for Retribution Paladins to maintain their mana without Spiritual Attunement in raids. Will it be enough ? We'll see.
