Trained these Loras with 40 hand picked images from Boorus under Anything V4.5, should trigger fine with "armarouge" or "ceruledge" but also adding some booru tags and "pokemon, fire on head, fire on eye, cannon, swords" helps too.
Didn't try in any other checkpoints rather than anime based, so results may vary.
Also, if you see a lot of fire in the image, try to put in negative fire related terms like "fire, flames".
Values between 0.6-0.8 should work good.
