Node lock

Node lock was an abjuration spell that limited access to an evil node and rendered it undetectable by magical means.

Effects
Upon casting this spell, a spellcaster made it increasingly difficult for others to tap into the power of an evil node. In addition, it rendered the node immune to the effects of the spell locate node.

This spell was only available to those who were capable of tapping into node magic. Its effects however, could be readily dispelled by any spellcaster.
