Abby starts fighting off the illness on her second day of suffering its symptoms, but by the third day it overcomes her body's natural defenses temporarily, making her feel even sicker and more shaky. However, by the fourth day her elven vitality starts to assert itself over the fever again, and her symptoms fade with the fifth day of rest.
[sblock=ooc]Still waiting on a reply from Fayne with new rolls. I'll check my notes and stuff later to see how much the group needs to spend for its room and board, but right now I've got other stuff that needs to be taken care of today. Evanar will recover naturally from the remainder of his poison ability damage over the course of the group's rest over a few or several days, depending on circumstances.
Abrielle suffers 3 more temporary Dexterity damage and 1 more temporary Constitution damage, but overcomes the Filth Fever afterward. By the end of the fifth day, she's recovered from all the ability damage and the disease itself. If she goes back to adventuring before the fifth day of rest, she'll still have some ability damage lingering until the end of the fifth day.[/sblock]
