Trivia[edit | edit source]

  • The Box of Friends seems to resemble the Lament Configuration of the Lemarchand's box from Clive Barker's Hellraiser.
  • Might be a very obscure reference to a Yu-Gi-Oh! card with the same name.
  • This item used to have a recharge time of 2, until an update on November 4th, 2015.
  • When playing in Korean, this item still has a recharge time of 2.
