The fearsome Lahn might not be upgrading her outfit but she is getting ready to experience an upgrade to her functionality.  Pearl Abyss is showing off the upcoming “awakening” for Black Desert’s Lahn. While the character class currently uses a crescent pendulum, presumably purchased on sale at Target, once she’s awakened she’ll upgrade to crimson glaives.
These glaives will come with all sorts of new skills, such as furor, deadly dance, tailspin, soul raid, and bloody stride. When the update goes live tomorrow, players can unlock Lahn’s improved weapon by going on her awakening quest.
