- This page is about the Vena added by Ztones. For other uses, see .
The Vena is a block added by Ztones. It is purely decorative.
A Vena block (or blocks) can be converted to another Vena block (or blocks) by holding alt-ctrl and scrolling with the block in hand. Alternatively, an Ofanix can be used in a Crafting Table to convert them, which is more useful for automative purposes.
