This is an Illustrious lora for Kairos Fateweaver from the Warhammer game series.
A weight of 1 to 1.5 works well with this with most models. At a weight of 1 it still looks good, yet there is only one head. And when one moves the weight to 1.5 the second head shows up more often. Sampling Steps of 15 to 35 works well with most models, as does a CFG Scale of 5 to 7.
Prompts for this lora are ( Kairos Fateweaver, Tzeentch, raven_bird, ). Adding additional terms like ( two headed, long necks, sorcerer robe, sorcerer, glowing eyes, ) can help make the image or improve on its look.
