Howdy!

It's a massive project, so forgive the massive novella of a post.

Some folks used a cut-and-repin of a Mistral shadow guard, an Asajj Ventress from GaW, a Nightsister from Univ. set, or of the Human Force Adept from A&E,
though you could use a heap of Bones miniatures or D&D, pathfinder etc minis... just depends on if you're going for that "Lily-wan esque" look to the nightsisters or the "Marvel StarWars Comics" look, or the TCW look hehehe
For the lightning, some used an Electro heroclix figure, though with the new heroclix and shapeways stuff, you could get all kinds of effects if you wanted to. Zatanna or some of the hidden ninja, or even streetfighter heroclix might do the trick.

I don't know how others achieved that glow-y hand on their Nightsister Possessed Felcors, but maybe that was with a translucent Hulk toy or Bane toy?
(you might be able to use Vorbla's own or some other clear plastic to form that effect a different way?)

For the chains and roping, I recommend searching for some of the old White Dwarf W40K
how-to guides, on possessed chaos chains for the iron hands, or how they achieved the effects for LOTR minis and the Elves;
you might be able to use ordinary 1mm/0.3mm chainlink from a craft store and some florist wire/twist-tie wire to glue the chain to the armature, creating those flail-y chains from the RPG description and novel appearances ("Nightsisters tormented their Rancors and dressed them for war; Yoda was not intimidated by their size..." etc from the Nightwitches/sisters of Dathomir)

The articles on the Mumak Howdah and how to convert dinosaur toys to Beastmen/Horadrim etc... you might find also of use
a local who made a stunning mumakil and huge orc stuff said the trick was to use thin pleather or vellum sheets and glue those together to make the vine-effect. Initially, the Mumakil didn't have a howdah, it was a forgeworld exclusive, and people just used sailing model sails and rigging to remake the howdah.

do you have some pictures of other customs, or a sketch of what you'd like to see happen?
(just a mud map'll do, it can even be photoshopped from a picture of the Felcor).
or, a still from TCW episode?

I think a few folks around here had some good ideas for that Bull Rancor,
mutant rancor,
and terantatek

Also, there are 4 3D printed Rancor models in .obj/.stl on the web, and it's to-scale with our rancor...
maybe you'd like to give that a look into, if you wanted horns and other addons?

Goodluck, and it's an awesome custom to be building.

check out my custom of the Night-Cor, on the 4th page of my customs thread

I cut the riding Felucian at the waist.
cut an Earth Shugenja* in half.
glued the top half of the Shugenja to the bottom half of the Felucian.
Lighting is from HeroClix Electra.



*D&D Underdark set, #3

good luck

Very cool! Great job!

@kobayashimaru: Thanks for the kind words and encouragement. I really love playing and therefore looking for new ways to make it interesting. I am a huge Nightsister and Dathomir Witch fan, so every time a new V-set piece comes out, I look for ways to ensure I have at least one custom for it. This was a dicey undertaking because if I am wrong at any point, I am left with broken pieces and therefore I have to find a way to fix it. I had good advise and took my time with this one, so it worked out well. Thanks to you all who offered advise.

The lightning was simple enough. I used a single thin film of al. foil. I rolled up a few pieces and twisted them together at the bottom to give the appearance of the Nightsisters hand wrapped in the lightning. I than removed the hand from the Earth Shugenja, and glued the lightning in place. I will eventually bend the foil a little more to give it a lightning look, as opposed to a cactus look.

The lightsaber came from a spare Dark Side Acolyte I had. I have just placed an order for 1/16" colored acrylic rods from Stevens International. I will be using these in the future for lightsabers. Heres the link for anyone who is looking for some.

My next task is to take these:

Aspect of Loviatar, D&D Night Below #26 and give her a Githany look.
Lords of Madness #43 Shadar-Kai Witch and give her a Asajj Ventress, Nightsister look
and take my Indy #062 Yukio x3, Indy #060 Shi x3 and my Indy #010 Scarab and give them a Nightsister feel. I will try and post pics when I get time.
