New mounts
The build adds 5 mounts. Where the client records how a mount is obtained (its source text names the vendor, drop, quest or achievement), that fact is printed as the game holds it; a mount without one is listed by name only.
Cerulean Prideclaw (Trading Card Game). A fierce and loyal mount that will accompany you on all your journeys.
Veteran Adventurer's Loyal Companion (Trading Card Game). When it is time to answer the call to adventure, this bear will be ready to take you there.
The build adds 73 items. Slot and binding come from the item record itself.
waist items: Al'Aketh Zealot's Belt (epic, bind on pickup); Shen'dorei Magister's Belt (epic, bind on pickup); Shen'dorei Peacekeeper's Belt (epic, bind on pickup)
feet items: Al'Aketh Zealot's Boots (epic, bind on pickup); Shen'dorei Magister's Boots (epic, bind on pickup); Shen'dorei Peacekeeper's Boots (epic, bind on pickup)
back items: Al'Aketh Zealot's Cloak (epic, bind on pickup); Shen'dorei Magister's Cloak (epic, bind on pickup); Shen'dorei Peacekeeper's Cloak (epic, bind on pickup)
hands items: Al'Aketh Zealot's Gloves (epic, bind on pickup); Shen'dorei Magister's Gloves (epic, bind on pickup); Shen'dorei Peacekeeper's Gloves (epic, bind on pickup)
head items: Al'Aketh Zealot's Helm (epic, bind on pickup); Shen'dorei Magister's Helm (epic, bind on pickup); Shen'dorei Peacekeeper's Helm (epic, bind on pickup)
The build adds 143 spells. Spell records are the noisiest family in a client build (every new item effect, aura and NPC ability is one), so the names below are examples and the true count is the number that matters.
The build adds 2 creatures to the creature table: the NPCs, bosses and critters the new content is built from. Spawn locations are server-side and are not in the client, so only the names are known.
What each spell listed above is and who uses it, read from the current game data: school, cast time and duration, the skill line or Adventure Guide boss it belongs to, and its tooltip with amounts left out (they scale with level and gear).
Bear Form Changed in this build: tooltip text and aura text. Physical, instant. Taught through the Druid skill line. Current tooltip: “The act of shapeshifting frees you from movement impairing effects.”
Sticky Bombs Changed in this build: name and tooltip text. Fire, instant. Name before: “Sticky Bombs” After: “Bombardment” Current tooltip: “After a delay, the bombs explode inflicting Fire damage to the target and enemies near the target.”
Cleave Changed in this build: tooltip text. Physical, 2 sec cast.
Before and After: Spell Values This Build Changed
Cooldowns, durations, cast times and schools that differ between this build and the one before it, each side read from its own build.
Each World of Warcraft game build is compared field-by-field against the previous build of
the same version line. Added, changed and removed records are read directly from the client
database, not from patch notes. Prices shown are the game's own vendor values, formatted with
live coin denominations; where a value is unknown it is left blank rather than guessed.
Counts are the true totals for the build; where a heading reads "40 of 11,892" the rows
under it are that many examples, and a record the client has not named yet is left out
rather than printed as an id. A removed record is shown by name without a link, because
the entry it pointed at is gone from the client. Every build lands in the
patch news feed the day it is ingested.
