This is LoRA, which gives you a toy hammer that only makes noise when you hit it, but doesn't hurt that much. Trigger words are piko piko hammer, toy hammer. The weight is recommended to be around 0.8. Trigger alone is fine, so holding is your choice. Illustrious version is trained based on Illustrious-XL 0.1, so there is a possibility that other Illustrious merge models or Noob merge models can be used, but we have not verified it.
