Node Preserver is a research item accessible on the Basic Information tab of the Thaumonomicon.
Effects[]
Completing this research will force players to leave at least 1 point of vis in each aspect behind when a player taps an aura node with a wand. This prevents the aspects of a node from being drained completely, thus preventing the node from sustaining permanent damage such as completely losing aspects or decreasing in brightness.
This effect does not apply when the player is tapping a node using a wand that has a core made of mundane sticks and/or caps made of iron or copper. (Note: Thaumcraft 4 does not add copper to the game on its own, but if it detects that another mod has added copper, copper wand caps and their associated recipes and research will be added automatically.)
A player may choose to override this effect to completely drain a node of its aspects if they tap it while sneaking.

Full text[]
You now have better control over the amount of vis you draw from nodes. You will always leave at least one vis of each aspect in the node, unless you are sneaking.
Be warned, this level of control is not possible when using wands crafted from normal wood and iron.
