Similar to Knockout Gas Swap. Doesn’t work against Robots (a "robot" is either a specific template or is defined by the character's voice ID; cf. ffxextras.py, under mechs=() for customisation) or Zombies and has no gas cloud FX. Fliers will fall to the ground.
Note: To approximate the visual feedback available with built-in disabling effects, the victim suffers from power nullification for the duration. This also allows you to cure the character by spending a hero point or by using a secondary-state curing power.
