Thunderstruck wood

They were piled together to build this dragon's lair within the city ruins. They had tremendous medicinal effects. Thunderstruck wood was jet black in color and looked like ink jade. Additionally, there was a lightly colored line upon it with a number of leaves. The leaves were still verdant and jade green with lingering vitality despite the passage of the years. The Thunderstruck Wood contained inherent vitality. A miraculous aspect of this item was that destruction and rebirth coexisted within. This type of wood was too rare because thunderstruck trees would usually die directly.
