Wooden Tendrils contains information about the Mystcraft mod.
"Wooden Tendrils" is a terrain modifier symbol that adds large, snaking tendrils made of oak logs to an age. Symbols such as this add visual appeal to ages. These tendrils are a good source of wood, though gathering it is considerably more difficult than simply growing a tree farm. A very useful tool to gather wood is the Axe of the Stream (Thaumcraft) with an unbreaking enchantment, as durability is used for each block, if enchanted with a good unbreaking, one block could be broken and the entire inventory filled with wood.
