How to make Sketch not suck

Hey folks! I'd like to share with you all some code to improve the Sketch command. Sketch is an interesting ability hampered by two things: it uses the monster's stats rather than Relm's, which are generally really low; and the selection of available attacks are often outright garbage. The latter is fixable with FF3usME, but the first requires some code changes to fix.

With this patch, Sketch will use the attacker's stats (Vigor and Magic for physical or magical attacks, respectively).

Code:

hirom
;header
!freespace = $C2A694

;Put attacker level [or Sketcher if applicable] in $11AF
org $C22C21
PHX                  
LDA $3417       ;Get Sketcher
JSR newfunc     ;New code
LDA $3B18,X     ;Level
STA $11AF       ;Level
PLX                    
RTS                  

org !freespace
newfunc:
BMI .exit       ;Branch if no Sketcher
TAX             ;if there's a valid Sketcher, use their Level for attack
LDA $11A2       ;Spell Properties
LSR A           ;Check if Physical/Magical
LDA $3B41,X     ;Sketcher's Mag.Pwr
BCC .magical    ;Branch if not physical damage
LDA $3B2C,X     ;Sketcher's Vigor * 2
.magical
STA $11AE       ;Set Sketcher's Magic or Vigor
.exit
RTS
