Use this model to add amazing leather belts to your characters, showing up some colorful health potions. Once you got your "normal" character, you should use an inpainting friendly model (I used STABLYDIFFUSED MAGNUM but I guess many others will work), go in the INPAINTING section, modifying your prompt like I suggested in the sample images and changing the settings, to get the desired change in a very short time. Enjoy!
