While Mythic Odysseys of Theros is not a valid resource for Adventurers League play, the team at Wizards of the Coast has used it to make a change to the Triton race — granting Triton characters the Darkvision trait. This is an intentional change to the race itself, and the Wizards team will be updating Volo’s Guide to Monsters to reflect this change. As a result, Adventurers League-legal Triton characters do now have darkvision.
