Join the path of discovery in Season of Discovery Phase 3. Beginning with weekly resets, players get the benefit of the Discoverer’s Delight experience buff*, which increases experience gains by 150% for all players through level 39 and 100% for players level 40-49! It’s a great time to join Season of Discovery, whether you’re just joining in the fun, or creating and leveling a whole new character.
Players can also visit any innkeeper in the capital cities to turn the experience buff off or on. 
*Experience buff not available in other WoW Classic titles or modern World of Warcraft.
