Phero's Sigs

Recently acquired PU #1, giving me 40 extra points. I'd like to spend them on the following signature:

Compound A0016: A viscous liquid compound that interacts in a bizarre way with other creatures and objects on the net. The compound identifies the scent of the one sprayed, then forms a transparent gaseous cloud around the target. The affected is shielded from damage as the cloud fluctuates from gas to nearly solid goop, splatting harmlessly to the ground once its job of absorption is done. Dharma also uses this as a nice way to test other, mixed in compounds, which are, of course, highly unstable. [20 HP barrier + glitch, 1 TCD]

That ought to be 40 points even.
