The trigger phrase is swrncrmnst creature.

Add bipedal to make sure that rancor will stand on two legs.

This lora will generate riders on the rancor, sometimes when not expected, it can be prevented with negative prompting.

For me the 0.7 or 0.8 weight worked best.

V2.0 update:

Corrected the data set, so all images were used in the training and changed the trigger word to swrncrmnst . The monster is now more varied, however it still has a rather big problem with generating a double jaw in the realistic models.
