Wurtfoil is perhaps the singlemost important herb. As explained in the sections on challenging and bloodlust, it is possible to be so harmed by death that your skills dip below their maximum effectiveness. This causes both loss of abilities and loss of effectiveness and all mortals strive to regain any lost skills as quickly as possible. Though the Gods may restore skill losses should they see fit, the most common and acceptable way is to take the wurtfoil herb or attend a wurtfoil brew. Rangers and Animists are the only guilds able to pick and prepare wurtfoil, and the Animists Guild hold regular wurtfoil gatherings where all present receive the gift of this herb and the restoration of the mortal bodies.
