Special: When a victim appears to be immobilized or incapacitated, a Lipophage will attach itself to them, causing 1d4 damage. Once attached, the Lipophage will then begin to extract all fatty tissues from their victim. This extraction process causes an escalating amount of damage the longer it goes on, increasing by an additional 1d4 each turn until either the bloated things floats off in a dazed state of contentedness, or the victim dies, which ever comes first. Every 40 hit points consumed in this manner grant the Lipophage one additional HD. There is no known limit to the size these things can attain, so long as they acquire enough fat to feed upon.
Sulking, skulking, smooth and slippery, Lipophages are disgusting nuisances few ever take seriously until after they're seriously injured or incapacitated. Cowardly scavengers, the amorphous things pulse and throb as they squish and squiggle through the stale air of the sewers, tunnels and caverns where they proliferate.
Old wives' tales hold that the Lipophages develop as blobby lumps of pulsing pink flesh arranged along a thick vertical stalk, much like Brussels sprouts that grow deep underground in areas of contaminated soil where hateful slimes or Spectral Brine has been allowed to accumulate and fester.
There is a wrinkly, blue-gray variant or sub-species of the more common Lipophage that specializes in extracting brains from their still-living prey. These creatures, tentatively named 'cerebrophages,' are both more aggressive and a good deal more cunning than their more placid cousins.
