	/// <summary>
	/// 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.
	/// </summary>
