An ashine is a creeper and parasitic ivy-like plant that grows along trees in forests. Its yellow-spotted shoots prepared as infusion make easier to resist to the bites of lycanthropes in order to avoid catching this disease. One also said that the very smell of this plant repels lycanthropes, but this ability is not really proven.
Absorbing an infusion of ashine gives a +2 bonus to Constitution saving throws against being afflicted by lycanthropy. The infusion is active in the organism for 1d4 hours.
