ParchArt is an embedding for Stable Diffusion 2.0+ Parchart should be considered a talented artist who has imbibed far too much absinthe. He works primarily in ink on whatever scraps of parchment he can find and occasionally pulls out some watercolor paints. He loves to write on his work so you'll see a lot of random annotations and text. He almost never gives you exactly what you ask for or expect but keep trying - some of what he produces is quite compelling.

All of the examples below were using DPM++ SDE sampler, 20 steps, cfg scale 7
Other samplers can have dramatically different kinds of outputs. Euler samplers will be often be particularly softer, fuzzy kinds of images.
Trigger the embedding with 'ParchArt'
I recommend keeping prompts fairly simple. I.e., Prompt: malevolent fae king portrait by ParchArt, iron crown with inset gems | Negative prompt: duplicates, extra body parts, extra head
Lots of details will just make for more simplified bland output, generally. This is something of a chaos machine and makes Stable Diffusion behave rather differently than I am accustomed to, and I sometimes go through a lot of lame outputs before I find something I like, but the keepers are really worth the hunting, for me.
