Today I was reviewing my sorceress spell list for before our game tonight, and I came to the description of the 1st level spell "Touch of Gracelessness", specifically the text that describes the effect.
According to the online SRD it reads as follows:
The target takes a penalty to its Dexterity equal to 1d6+1 per two caster levels (maximum 1d6+5). This penalty cannot drop the target's Dexterity score below 1
I've been leaving this spell on the side because recently we've been facing undead creatures and other foes that are immune to ability damage, but I just noticed that it is called a "penalty", and doesn't mention it being ability damage per se.
So the question is this: Is the dexterity penalty caused by Touch of Gracelessness ability damage, ability drain, or just a penalty that cannot be avoided by immunity to such effects?
