Like her teammate Legion, Clarisse’s battles are available in three difficulty modes: Hard, Lunatic, and Infernal. Beating the Infernal map gives you another 4★ copy of Clarisse and 2,000 Hero Feathers. Unlike Legion’s battles, however, her maps do not feature enemy reinforcements. She also does not have an associated summoning focus banner.
Clarisse’s Grand Hero Battle will be available for one week until 5 July at 6:59am UTC. Do your best to defeat this assassin and put her skills to use for yourself!
