XC2: Elma Redux in
this challenge is actually not difficult at all; to win, all you have to do is spam corvin's art galactic strike on zeke which will allow you to evade absolutely everything. however, getting a speedkill is a little trickier.
first, you must deal out as much damage as possible with corvin, while abusing elma's light weakness with patroka. after a certain point, you need to use a blade special on morag and swap to an orb master common blade at the end (so you dont lose too much of corvin's damage). tora also must break at exactly the right moment so that it lasts throughout the entire chain attack, so you can abuse the fusion combo damage boost. if elma deflects too many chain attack hits, she will not die.
my fastest time for this challenge was 1:33 but i wasn't recording during it. it takes a lot of luck hoping that tora will switch and break at the right moment though so i'm satisfied with this time for now. could've been faster but i mistimed patroka's special.
