This LoRA makes it so that the subject in question has fused legs, akin to a mermaid tail, but without the tail fin and with a foot instead. Depending on the LoRA weight you use it can also add footwear so it looks like a Mermaid on land with different challenges. I'm not fully satisfied yet so more versions could become available in the future, but it does generate it very consistently now.

Trigger words are;

monoleg, sealed legs, fused legs, skinsealed, unileg, unified legs, skinsealed legs, one leg, merged leg

With " footwear on leg" as the trigger if you want footwear on it.

Feedback is very welcome :)
