If you’ve never checked out the art of Domenico Neziti, you’re wrong. Stop being wrong. Seriously. He’s worth your time. I’ve mentioned this before in another post that includes more links. I see work like this, and it just screams to be used in a game.

Boldogs are powerful demons who are often deified by orcs. A boldog somewhat resembles an orc, but they are larger, stronger, and obviously more intelligent as evidenced by the cunning malevolence that burns in their eyes. The spells of casters below 3rd level do not affect boldogs, and these demons are 35% immune to spells from more powerful casters. In battle, boldogs fight with swords and wield shields. A boldog’s gaze causes disease, putrefies food, and poisons water.
