;Haven't tested this out, might work

CalculateDamage:
  ld hl,(strength)
  srl h
  rr l
  ex de,hl
  ld hl,(attack)
  push hl
  add hl,de
  ex (sp),hl
  inc hl
  push hl
  dec hl
  ld a,3
  bcall(_divhlbya)  ; or call, if not using 83+ ion
  ex de,hl
  pop hl
  or a
  sbc hl,de
  ;Damage spread won't exceed 255...
  ld b,l
  call ionrandom
  pop hl
  ld d,0
  ld e,a
  add hl,de
  ret

;This may work.
