until 2022. In 2021, a second Alternate Campaign was launched – the Ravenloft: Mist Hunters storyline which ran until March 2022. In September 2021, with the 11th season of organized play, the categories were restructured again. Campaigns were divided into Expansion Campaigns, Event Campaigns, and Adapted Campaigns. Expansion Campaigns feature "a set series of adventures in a connected storyline"; the original Seasonal and Alternate Campaigns were moved to this category. Event Campaigns feature "completely independent storylines from official D&D products" and are the analog to the previous living campaigns. The ongoing Dreams of the Red Wizards is now considered an Event Campaign. Adapted Campaigns are any official D&D product, such as hardcover adventure modules, with the corresponding Adventurers League rules guide. In March 2022, Baldman Games began running a ticketed Adapted Campaign featuring Critical Role: Call of the Netherdeep (2022) as part of the D&D Virtual Play series. Rules The D&D Adventurers League requires both players and Dungeon Masters to keep official logs of their play experience and it includes an additional ruleset for play in order to facilitate the ability to "drop in or out on a session by session basis". This includes unique rules on experience points, magic items and gold. In 2018, "the admins of the Adventurers League announced a sweeping overhaul of the rules, designed to change how players earn XP and treasure". Several magic items were removed from the game, and players now gained "advancement checkpoints" and "treasure points" which they could trade for level advancement and magic items respectively. In 2019, with the 9th season of Adventurers League, these checkpoint rules were replaced with new character advancement and magic item rules and then adjusted in 2020 with the 10th season of Adventurers League. This unique ruleset also governs character creation. Initially, players were limited to the character creation rules in the Player's Handbook (2014) along with a single other "officially allowed book of their choice". "This was done to allow DMs to ensure their games were balanced and avoid abuse of multiple rulesets". In 2021, the rules for character creation changed to allow players to use any of the following sourcebooks: Player's Handbook (2014), Volo's Guide to Monsters (2016), Xanathar's Guide to Everything (2017), Mordenkainen's Tome of Foes (2018), and Tasha's Cauldron of Everything (2020). Additionally, "setting-specific AL campaigns [...] have access to books created for those campaigns like Sword Coast Adventurer's Guide or
