Silverbark is the bark from a Silverbark tree. Its properties vary widely but it is mainly used for medicinal and religious purposes. It is a holy tree and when the bark is burned it does so with a white cored silver flame. This is an anathema to the undead and the corrupted. Anything unnatural fears and is vulnerable to the silverbark’s flame. Druids often use silverbark for shields or armour because it takes to enchantments well and is hard and durable even when thin.
