Sometimes got lucky and had spider related prompts give these but it wasn't consistent. So voila I made a lora for it. Unfortunately it is kind of weak and is a bit hit or miss with some character and style loras. Still it does what it's supposed to.Also Sp1der l3gs is the trigger phase but on it's own it often isn't enough to manifest so I recommend the following tags: Arachnid,Arthropod,8 limbs,monster girl.
Note:From Side doesn't change the pose but it does tend to make the legs match the characters hair color.
