was playing with nero and remembered a very handy few tricks for people like devil trigger invulnerability cancel shuffle into charged shot or callibur cancel to do them do as follows
against a boss or enemy just before there attack hits dt with nero as during the trigger activation animation he is invincible and the attack wont damage him then just deactivate dt for the shuffle cancels do the backwards input for shuffle then jump and forward analog and y or triangle and you perform a callibur on the ground do shuffle input while charging blue rose and jump shoot it knocks you back you can even cancel shuffle into table hopper hope this helps ew players
