Narvalous has sent word that a new feature has been added to Chrono Wars. Called "dragon arm", the system allows players to literally have a dragon arm attached that gives access to the awesome power of dragons and enhances attributes as well as adding new attributes of Grit, Block & Block Rate. To show how the system works, the team has put together a new video.
Dragon Scales are needed in order to upgrade Dragon Arm, and they can be obtained from the Dragon Treasury Challenge. You can enter Dragon Treasury after reaching Lv. 59 or above, and the challenge is open all day. Conquer each floor of the Dragon Treasury and upgrade your Dragon Arm! The higher the Dragon Arm level, the more attributes and BR you will achieve.
