This character has little backstory, relatively no fleshing-out.
How does she depend on her poisons to get her out of tough spots? It was my belief that poisons must be ingested or breathed in. How does she fight with poison? Splash it in the enemy's face?
Why is she so good with poisons?
Nearly every primitive culture has had rituals and celebrations to guarantee the proper passage of the seasons and to ensure the fertility of crops and animals. Oversight of these ceremonies was generally the provenance of local kings or priests.
Suppose that the adventurers dispatch one of these fellows. The local peasants may become hysterical, fearing famine and death will stalk the land. Alternatively, they may want one of the new heroes to become king. For a while, this can be a good thing, but the first time that the crops fail, the superstitious locals will want to sacrifice their new leader.
