Necrotic Raincaller (Fun)

Appearance
A skeleton covered in liquified flesh with only the veins still intact and pulsating with blood, quite nasty to look at.

Information
When an Un-damned survives the death of the master who summoned it and finds a new source of power, it reaches a higher form able to communicate with the concept of undeath itself. It then begins to change, flesh becoming liquid and spreading over the old bones, slowly seeping into them as the evolution continues. As long as it remains in this stage, it will attempt to find safety in numbers and rarely leave its base, as distancing itself from its source of power for too long spells a certain end to its already desperately clinging existence. For normal Abyssals it would be a really unlucky day to run into one of these suckers, but at this point you are so stupid I will just spam what is absurd at you.
