Detect Invisibility

When the magic-user casts a detect invisibility spell, he or she is able to clearly see any objects which are invisible, as well as astral, ethereal, hidden, invisible or out of phase creatures.

Detection is in the magic-user's line of sight along a 1" wide path to the range limit. 

The material components of this spell are a pinch of talc and a small sprinkling of powdered silver.

Except as noted above, this spell is the same as the second level magic-user spell, detect invisibility (q.v.).
