Tiger snakes are most commonly found on the continent of Dorian. They resemble the basilisks, which are ridden by the Phantoms in order to enter this realm from the Astra Universe. Due to their appearance, they are the most commonly sacrificed animal in the world, in order to please the Phantoms at their Altars. Their venom, while powerful, is only considered deadly to small children and the elderly, but it is known to cause paralysis.
