- This page is about the Obsidian Rod added by Thaumcraft 5. For other uses, see Obsidian Rod.
The Obsidian Rod is a component added by Thaumcraft 5. It is used to create Wands- it can store 375 Vis. When the Terra Vis in it drops below 50%, it will replenish, without drawing from the Aura.
A wand core chiseled from obsidian has slightly greater storage potential than greatwood cores. What makes it superior to greatwood cores however is that if the level of Terra stored inside it drops below 50%, its will slowly replenish without the use of the aura.
