Decided to have grey seer that would be different to standard one - soo I made him a Lich.

It's middle-level conversion (as far as non-greenstuff convertions go) - used skull from stormvermin kit, added horns from grey seer, sculped-up plastic a bit to make his arms and feet skeletal and added (not visible on this pic) neck-spine.

Little glow added around warpstone.

You can also notice pet-rat of Squickdor's being tied to one of his horns.
