Bonus Artifact XP Week! This is the week you have been waiting for! All week, Artifact XP gains are doubled when you fortify your Artifacts. That means any time you're using Nth Metal to add XP to and rank up your Artifacts, those gains will be doubled. Thinking about jumping into that new Artifact? Getting ready for Birds of Prey? Have a bunch of Nth Metal ready to go? Now's the time. This week - from Thursday, April 9, 2020, through Wednesday, April 15, 2020 - all players will receive DOUBLE Artifact XP when fortifying Artifacts. For more information about Artifacts and how to rank them up, refresh your memory with the Artifact guide. Please note: the Bonus Artifact XP Week begins this Thursday with daily server restarts, and lasts through Wednesday to daily server restarts next Thursday morning.
