Obtained via Mymber's Heart Valve 

Nullifies one chosen Radiation Sickness in a Rad Sick Ixi. If a Mymber is equipped, that Mymber cannot nullify a second Rad Sickness.
In both non-Rad Sick and Rad Sick Ixi, has a 30% chance of temporarily nullifying Radiation Sickness effects in other Ixi in certain situations: in Breeding, this Ixi has a 30% chance to deactivate Radiation Sicknesses that give breeding debuffs (Infertility, Recessive, Fever Dreamer, etc) in the other partner. In activities, if depicted with another Ixi that happens to have a Rad Sickness that can impact their roll, there is a 30% chance this Ixi can nullify their Rad Sick traveling companion's ailment for that roll.
This ability also grants a resistance to certain Temporary Conditions - this resistance applies to both the owner of the Mymber's Heart Valve as well as any other Ixi depicted in the piece.
