Infrasonics is a Blue Mage skill in Final Fantasy XI learned from Lizards. It lowers the evasion of enemies within a fan-shaped area originating from the caster. It costs 4 Blue Magic Points to set. When set, it grants INT +1. It takes 5 seconds to cast and can be recast every 120 seconds.
Infrasonics is also an enemy ability used by the Lizard family.
