  ///   This special move represents a significant change to the use of poisons in Age of Shadows.
  ///   Now, only certain weapon types � those that have Infectious Strike as an available special move � will be able to be
  ///   poisoned.
  ///   Targets will no longer be poisoned at random when hit by poisoned weapons.
  ///   Instead, the wielder must use this ability to deliver the venom.
  ///   While no skill in Poisoning is directly required to use this ability, being knowledgeable in the application and use of
  ///   toxins
  ///   will allow a character to use Infectious Strike at reduced mana cost and with a chance to inflict more deadly poison on
  ///   his victim.
  ///   With this change, weapons will no longer be corroded by poison.
  ///   Level 5 poison will be possible when using this special move.
