This is an Illustrious lora for Forcefields.
A weight of 1 to 1.5 works well with this with most models. Sampling Steps of 15 to 35 works well with most models, as does a CFG Scale of 2.5 to 5.
Prompts for this lora are ( forcefield, transparent energy barrier, ).
Keep in mind that when using the term dome while using some checkpoints can make the checkpoint think it is okay to add a dome over a character's head or have a dome float above ground. Prompt accordingly.
