You need to find :
'hiteffect\hit_4_fire_hit_X.efp' and 'fire_gigongta_keep_X.efp'
And replace With
'hiteffect\hit_4_fire_hit_N.efp' and 'fire_gigongta_keep_N.efp'

Don't Add The ' When Your Editing!:!:
X = Your Imbue book. (Eg. A = 1st book, B = 2nd book, etc.)
N = The Imbue You Want (Eg ~ ~ ~ As Seen Above)
