if u try to L1 + X on console , u cant pull off phasejump anytime
BUT , if u change X to R1 . u can phasejump but still u need to time it right , take a bit of practice .
if u dont want to press L1+R1 to jump , go to ps4 accessibility > button assignment > switch X+R1.
for whatever reason the game require a L1+R1 input in order to pull it off so once u set your thing like above said , your X will be inputting R1 which allowing you to phasejump
