  PENGENALAN :
  Secara default, RPG Maker VX Ace tidak support multi element dalam database.
  Yang ada hanyalah satu element untuk satu skill. Script ini ngebikin kamu
  bisa bikin satu skill memiliki banyak element (misalnya, fire spear,
  elemental rage). Kamu juga bisa memilih kalkulasi perhitungan ratio
  elementnya tar di konfigurasi.

  CARA PAKAI:
  Jika skill mempunyai element fire, dan senjata mempunyai element slash, maka
  skill sudah mempunyai 2 element. untuk menambah element, gunakan notetag
  pada note di database skill / item :

  <elements id: x>
  <elements id: x,x>

  TERMS OF USE :
  Credit gw, TheoAllen. Kalo semisal u bisa ngedit2 script gw trus jadi lebih
  keren, terserah. Ane bebasin. Asal ngga ngeklaim aja. Kalo semisal mau
  dipake buat komersil, jangan lupa, gw dibagi gratisannya.

  NOTE:
  Kalau mau nambahin ide untuk management element, langsung aja bisa komen ke
  blog gw di http://theolized.blogspot.com

    # Disini kamu akan memilih aturan formula perhitungan element. Sorry kalo
    # semisal perhitungannya terbatas. Kalo semisal kamu pengen kasi saran,

    # Well, ok jadi begini soalnya. Semisal sebuah skill mempunyai 2 element
    # dan sebuah(?) battler memiliki resistansi terhadap element itu adalah
    # 50%, 100%,
    # -----------------------------------------------------------------------
    # 0 : Cari yang paling gede
    # -----------------------------------------------------------------------
    # --> Resultnya adalah = 100%
    # -----------------------------------------------------------------------
    # 1 : ADDITION / PENAMBAHAN
    # -----------------------------------------------------------------------
    # Rumus = 100 + (element_1 - 100) + (element_n - 100)
    # --> 100 + (50 - 100) + (100 - 100) = 50%
    # -----------------------------------------------------------------------
    # 2 : AVERAGE RATE / RATA-RATA
    # -----------------------------------------------------------------------
    # Rumus = total / jumlah
    # --> (50+100) / 2 = 75%
    # -----------------------------------------------------------------------
    # 3 : MULTIPLE / DIKALI
    # -----------------------------------------------------------------------
    # Rumus = 100 * (element_1/100) * (element_n/100)
    # --> 100 * (50/100) * (100/100)
    # -----------------------------------------------------------------------
