Rabid

Strength .7-1.1 depending on style/sampler. Would stick to .9 and under for photo styles unless upscaling/hi-res fixing.

Main trigger a R4b135 rabid animal/thing

The R4b135 part is optional. Use just "a rabid" for a little less effect. "a R4b135 rabid rotting" is the opposite, and should let you lower strength a bit, especially with other LoRAs, but it can be extreme. Forewarned! I am also having some luck with R4b135 at the end_._

May want to use helper terms: open mouth, fangs, drooling, drooling from the side of the mouth, foaming at the mouth, frothing, bloody, hollow eyes, sunken/empty eyes, dark eyes, giant eyes, etc.

Animals with very unique features, like an elephant trunk, may need a little lower strength.
