I forgot to check the forums after maintenance. Anyway, there are 2 new boxes (250 Gold each) in cash shop for Sword 2. See Quinzel's V and Raiden's V for details and complaints about the low drop rate for the new costumes.
Quinzel's Surprise V includes Dragon Heart Recipe, Symbol of Aries, Lavender Costume (Selva), Wild Back hair (Nar), Asupplegion Costume (f/fig), and Mabro Metis Costume (m/wiz). Raiden's Box of Rage V includes Dragon's Fury Javelin (AR32 javelin), Elite Magnum (AR30 pistol), and Symbol of Virgo.
