Mixology Grants At Least 2 Potions - Season of Discovery Hotfixes for July 24th

wowhead.com:

Blizzard has posted hotfixes for July 24th, highlighting class and item tweaks from the last few days, including increased drops for Librams of Resilience and a nerf to Darkmoon Card: Decay.

• Items
  
  Burning Essences will now always drop from the Dark Coffer in Blackrock Depths.
• Libram of Resilience now have an additional chance to drop from certain bosses in Blackrock Depths and Blackrock Spire.
• When Might of Stormwind is restored from a Chronoboon, the buff will now appear properly in the tooltip and it will now correctly apply to the player's pet.
• You may now mount while Gift of Gob is active.
• Darkmoon Card: Sandstorm will now correctly hit enemies that are within line of sight, and not hit enemies that are out of line of sight.
• Darkmoon Card: Decay internal cooldown increased to 3 seconds.
• Pix Xizzix now offers the Drakestone caster offhands for 50 Undermine Real each.
  
  Developers' notes: While we don't intend to put everything of this nature onto the vendor, the offhands from Sunken Temple felt right to us.

• Mixology now always gives at least 2 potions as intended.
• Professions with adjusted level requirements for Expert and Artisan ranks have been returned to their original level requirements.

• Idol of the Moon tooltip updated for accuracy and clarity. The item's effect is unchanged.
• Idol of the Moon now correctly applies to Starfall and Sunfire.
• Idol of Brutality now correctly applies to Mangle (Bear).
• Idol of Ferocity no longer incorrectly discounts Mangle (Bear).
• Idol of the Dream now correctly affects Swipe (Cat).

• Players can now have only one Mana Shield active at a time. If an equal or higher rank of Mana Shield is cast on the target, it will overwrite the previous Mana Shield.
• Fixed an issue with Rewind Time where refreshing Temporal Beacon on a target after that target took damage, which would make any damage taken before the refresh not get healed by Rewind Time.
• Improved Arcane Missiles
