Sigbin, also known as Morgath's Goat
Below are Monster Stat Blocks on Foundry VTT. These are guidelines only. I regularly individualize named or important monsters.
The Order of the Lord of Chaos is well known to create hordes of undead to serve the nefarious plans of their god Morgath. Less well known is their experimentation or magical modification of common animals, creating monstrous entities.
This species results from exposure of the common goat to Shadow of Bukrai and various magical diseases. They are twisted, spiteful, cunning, and cruel creatures who like nothing more than destroying anything pure, innocent, or good.

Attacus, my man! I hope all is well with you. I love the concept here, evil goats. If I might offer up some suggestions, firstly a goat has to have horns (insert Black Sabbath guitar riff off here), remove fangs insert horns and add a headbutt attack. Instead of true invisibility the goat is only invisible in the shadows, and is able to leap from shadow to shadow, the goat should have also have reduced powers during the hours of daylight.
Hi MrGunn, thanks for all the suggestions. I have incorporated them all.
(Heavy death metal music sounds) Thanks for taking my suggestions, looks awesome.
