I would say a mod upgrade, 1 pt
Ionizing damage
you May equip another modification upgrade. (Maybe)
when a ship is hit by your attack place an ion token on one of the target’s Turret or Cannon secondary weapon, System or Tech upgrade. That upgrade is ‘ionized’ and is considered to be discarded.
Ion tokens placed on upgrades can be removed by spending a focus token,
Ion tokens placed by your secondary weapons or pilot or upgrade abilities may also be placed on upgrades instead of on a ship.
(this way self inflicted ion tokens can be moved around a bit as well or removed with an existing focus. Probably a boon to Rebel Scum tho....)
