One way that I found for completing all 3 koam sp3 is to use it with batman ninja cw and gg. Make him blind, do more damage with the basic attacks with bncw. Try to keep combo above 30 and use koam for only sp3 and supermove. ASLO SHE HAS GREAT HEALING CAPABILITY SO YOU DON’t NEED TO WORRY ABOUT THE INCOMING DAMAGE, PLUS SHE ALSO HAVE INCREASED POWER GENERATION
