LORA weight: 0 to 1 for IXL

This is a slider, Lora, so you can choose whatever weight you want, so experiment and find what suits you best. A positive weight adds abs. You can use even higher weights such as 8 and above it all depends on characters and checkpoints.

You can also add deepthroat to your prompt to make it have an even stronger effect.
