Colossal Leech

Leeches are unpleasant, but in the real world they are not dangerous to humans (aside from a very small chance of transferring a pathogen from one victim to another – where this is possible, the potential victim must fail both a Luck check and a DC 5 Fort save). Indeed, leeches have been used in medicine since ancient time, and loan their name to medicine as “leechcraft” and healers as “leeches”. The core rulebook offers statistics for colossal leeches, reproduced above. Leech swarms are horrific gatherings of normal -sized leeches, whereas giant leeches are roughly halfling - to human -sized.
