I've always been very fond of this little treasure gremlin, and no IL model existed of her from what I could find so I wanted to do one for her myself.
Note that this is my first ever uploaded model, and only the second model I've actually created so far. All of my image gens were done with WAI-NSFW-illustrious-SDXL 14.
The general guidance for genning is best gleaned from the images I've posted themselves, as the generation info attached to each is quite detailed. This model was trained on around 100 in-game images of Mia (from a series of 4k YouTube videos). the prompt "dq11mia" was used on *all* images during training, so it it may/may not be worth experimenting with some appearance prompts to see what is needed/what isn't, as this may offer more flexibility. You can also optionally add her "gold necklace" from her possessed/Gyldygga form if desired as images of her wearing it and the prompt were included in training.
Note that as she has a fairly brief appearance and role in the game overall and only exists in game in a couple of locations, capturing her in a variety of locations was not really possible. As such, scenes with complex backgrounds may not always come out so well. The primary issue I have had though is with her hands adding extra fingers, or generally just looking distorted. I'd encourage anyone interested to experiment with CFG/Steps and prompts etc. to get the best possible results in any case. Other detail focused Loras may also help alleviate certain issues but I haven't tested them.
Hope it works well for you still, and hope you enjoy!
