Frosted Wood

Frosted wood would be for spruce wood, or you could make it for all kinds of wood, but since the taiga forests have spruce trees and it snows, when it snows you could make it so the wood frosts or has bits of snow on it. you could also make wet wood for when it rains in other biomes, and wet would could be easier to break, and rotted wood could be for the logs that are shown as fallen trees you sometimes see in forests, are rained on alot and rot.
