Zappo said:PCs never use it. NPCs seldom use it. The reason is that a spellcaster can almost always find something better to do in his turn than *maybe* making another spellcaster waste a spell at the cost of wasting one yourself. Usually, it is used by relatively low-level spellcasting mooks who wouldn't know how to hamper the party otherwise, or by some outsiders that get dispel magic at will and are numerous enough that one or two of them can counterspell while the others fight.
