how to change the skill "possess"

My Apologies, I was in a hurry last time. But here's the Original code:

Code:

C2/1610: C0 08        CPY #$08       (Capture enters here)
C2/1612: B0 07        BCS $161B      (branch if monster)
C2/1614: B9 D8 3E     LDA $3ED8,Y    (Which character it is)
C2/1617: C9 0D        CMP #$0D
C2/1619: F0 20        BEQ $163B      (branch if Umaro)
C2/161B: BB           TYX
C2/161C: BD 58 3C     LDA $3C58,X
C2/161F: 4A           LSR
C2/1620: A9 01        LDA #$01
C2/1622: 90 02        BCC $1626      (branch if no offering)
C2/1624: A9 07        LDA #$07
C2/1626: 8D 70 3A     STA $3A70      (# of attacks)
C2/1629: 20 4D 5A     JSR $5A4D      (Remove dead and hidden targets)
C2/162C: 20 65 38     JSR $3865      (depending on $3415, copy targets into backup targets
                                      and add to "already hit targets" list, or copy backup
                                      targets into targets.)
C2/162F: A9 02        LDA #$02
C2/1631: 14 B2        TRB $B2        (clear no critical & ignore true knight)
C2/1633: A5 B5        LDA $B5
C2/1635: 8D 13 34     STA $3413      (save backup command [Fight or Capture].  used for
                                      multi-strike turns where a spell is cast by a weapon,
                                      thus overwriting the command #.)
C2/1638: 4C 7B 31     JMP $317B      (entity executes one hit (loops for multiple-strike
                                      attack))

and my code:

Code:

C2/1610: A9 C6                  LDA#C6              (Flare Star)
C2/1612: 85 B6           STA $B6        (Set spell/animation)
C2/1614: A9 02           LDA #$02       (Magic)
C2/1616: 4C 69 64        JMP $6469      (jump to subroutine C2/6469)

C2/6469: 85 B5           STA $B5        (Set command)
C2/6471:  4C 5F 17        JMP $175F      (jump to subroutine C2/175F)
