Get ready for massive Experience gains as World of Warcraft celebrates its 20th Anniversary! Starting October 22, leveling your alts has never been easier, with total Experience gains increasing by up to 75% and Reputation by 30%.
20th Anniversary XP Buff
Players receive an automatic 10% Experience and Reputation buff during the Anniversary event and must complete the repeatable Celebrate Good Fun! quest from Yllana every day to add another 10% to the total.
Warbands XP Bonus
For every character you have at Level 80, you will enjoy an additional 5% XP buff, stacking up to 25% times. This means if you have 5 Level 80 characters, you will be raking in a +25% XP bonus from 
Five Warband Mentors: The War Within.
War Mode Bonus
With War Mode enabled you will receive +10% XP and Gold.
Hallow’s End Buff
From October 25 through November 8, 
Unburdened will increase XP and Reputation gains by 10%. You will receive the buff upon clicking the Wickerman bonfire. This buff lasts for 2 hours.
Darkmoon Faire Buff
During the anniversary event, there will be two Darkmoon Faires, each bringing the 
WHEE! buff. This increases Experience and Reputation by 10% and lasts for 1 hour! This buff will stack with the anniversary event buff and you can get it by riding the carousel or roller coaster.
- First Darkmoon Faire: November 3-9
- Second Darkmoon Faire: December 1-7
If you do not want to return to Darkmoon Island every hour, you can purchase multiple 
Darkmoon Top Hats for 10 token prizes each, and they will provide you with the buff wherever you are. Thanks to FrankzzzD2 for the tip and additional fixes!
Draught of the Ten Lands Potion
Draught of Ten Lands increases XP gains by 10% for 1 hour but only works on characters level 49 and below.
Big XP and Reputation Gains – The Breakdown
Starting October 22, you will automatically receive a 10% XP and Reputation boost that can be increased to 20% every day by completing a simple quest. For each Level 80 character, you gain another 5%, stacking to 25%. War Mode grants +10% when enabled. Hallow’s End brings a +10% XP and Reputation buff between October 25 and November 1.
The first Darkmoon Faire will start on November 3, providing another 10% boost. Chars at or below 49 can get another 10% from the Draught of Ten Lands potion, leading to a total of +75% XP and +30% Reputation gains!
