Essential Wood

Regular
Transforms any intact wood into the magical essence of wood. Essential Wood is three times as strong as regular wood, with three times the HP and DR listed here HP & DR of Objects & Cover, and three times the ability to support weight. It is difficult to ignite with regular flames (Highly Resistant, according to the chart on p. B433), but once lit burns three times as long. It also burns hotter, adding an extra point of damage to each die (this will even increase the heat of Essential Flame!).
Manufactured objects made of wood can be turned into objects made of Essential Wood; living plants, however, may not be transformed.
