This spell when cast on an unoccupied space provides the visual effect, but when entered it does no damage and disperses, same problem when cast on a character.
Also- If someone is going to get around to fixing that problem with it, the DC is bugged to be stuck at DC 14 here (http://nwn.wikia.com/wiki/Talk:Glyph_of_warding#DC_bug) is a fix for it from nwn wiki.
Any comment? It just seems silly that johannes changed the spell and it doesn't even work.
