Umberhulks are some of the most iconic and awesome D&D creatures of all time, I'm a huge fan. These were in a group of minis from the Nolzur's Marvelous Miniatures line I purchased during a sale from MiniatureMarket. Nolzur's minis are made of a plastic that is harder than Reaper Bones material, but softer than every other line of minis I've had experienced with. They come pre-primed, but with mould lines intact. Which kind of renders the priming moot.
Assembly:
Very simple, as these came pre-assembled. I did remove the base it came with to do my own. Mould lines weren't bad and easy to remove. Some bits were a little bent, but nothing hot water couldn't fix.
Paint:
Primed with Badger Stynlrez primer, brushed on. The purple umberhulk miniature painted purley in oils. Mostly Winsor & Newton Winton line. Once dry, used Daler Rowney flourescent ink for the bright orange bits. The orange one was painted in acrylics, as I wanted to try doing a coconut crab motif. Used Reaper and Vallejo acrylics, and a toothpick for the small dots. Took a couple hours to paint the oils, then a few days to dry.
Both sealed with some matt varnish from Reaper Miniatures.
Base:
Custom made with cork, PVA glue, sand, rocks, etc. The mushrooms were hand made with hot glue and toothpick tips, painted with Daler Rowney inks. A few little flock moss bits glued in as well.
