395) Acme air solidity. In a situation where the ground under the wielder's feet for some reason falls away or is removed the wielder of this blade is able to continue walking on the air as if the ground was still there. This effect is dispelled the moment she looks down.
396) Acme damage impermanence. No amount of damage inflicted upon the wielder of this blade will cause _visible_ bodily or equipment damage upon her, other than a slight layer of soot on her face (which can be easily wiped away with a single hand gesture).
397) Acme impact resilience. Falling down from any height will cause the wielder of this blade to hit the ground flat, then bounce up into a standing position, without damage inflicted upon her.
398) Acme doom shadow. Any air based attack directed against the wielder of this blade will cause a shadow to appear beneath her. The shadow will grow in size as the attack gets closer. This doesn't make air attacks any easier to dodge, but it does mean that they are always detected by the wielder when they are launched.
