Node Sensitive

(Champions of Ruin, page 25, DnD 3.5)

[General]

You can perceive a node just by passing near it.

Benefit

You automatically note the presence of any node to which you are attuned within 30 feet.

Normal

A creature without this feat that comes within 30 feet of the outermost layer of a node can make a DC 20 Intelligence check to note the presence of the node. A creature with the appropriate Node Spellcasting feat can attempt either an Intelligence check or a Spellcraft check at the same DC to notice the node.
