It's a lora for Ceres Endorma from The Swordmaster's Son.
I trained it on hassakuXLIllustrious_v30WIP checkpoint, so other illustrious checkpoints that i promptly tested it's showing less effect even with bigger strength. If using hassakuXLIllustrious_v30WIP then something around 0.8 strength is seems good.
Note: As my not so brilliant brain have no idea how to properly prompt that mess of a dataset that i currently have, so it's not stable and well balanced. You'll have to play a little with keywords in order to achieve something that is not poor.
