Countering
Various poisons are not fatal and if properly treated, can be expelled from the victim's body. Numerous Teigu can assist recovery, prevent or even stop its effects. Such Teigu include Incursio, which could protect its user and help them recover from harmful toxins. Certain poisonous Teigu have special conditions that they have to meet in order for the poison to take effect. For example, Murasame can be fought off if the combatant avoids direct contact with its blade or protects themselves by encasing their body in armor. Additionally, organic Teigu as a whole cannot be affected by any poison or toxin. Babara Oreburg was known to have resistance to 600 kinds of poisons in her body.
