Does Siabries Sandtouch work on constructs and undead?

[sage20500]

Like the title says, looking at several fey creatures as potential stand ins for a plot that is supposed to draw the players into the beginnings of a throw down between a Dry Lich and the Fey. Sandtouch's ability states that any creature that the Siabrie damage's must make a Fort save or be turned into non magical sand. The only thing that makes it seem like this counts as a death effect is that it mentions only wish, miracle, or true resurrection can bring them back. But in their description they give it states that the Siabrie's mere touch is capable of eroding away both undead and constructs, so I'm not sure how Sandtouch is supposed to interact with creatures of any type that normally ignore Save or Dies.

It's transformational magic. You can use Baleful Polymorph or PAO on Undead & Constructs, Siabries can change them in to sand. Heck, Baleful Polymorph specifically turns them into a living being!

RAW, they take the damage from the touch as normal but do not have to make a fortitude save. Undead and Constructs are immune to effects that require a fortitude save and don't affect objects, and the Sandtouch only works on creaturres. However the touch attack damage and the sandtouch transformation are separate abilities, so they are subject to the former(which has no save) but not the later(which does.)

That also fits with the flavor text that their touch can erode undead and constructs.

Uh... since when are Undead not Creatures?

They are creatures, but they are immune to any effect that requires a fortitude save unless it also works on objects. It's part of their type. (http://www.d20srd.org/srd/typesSubtypes.htm)

Immunity to any effect that requires a Fortitude save (unless the effect also works on objects or is harmless).

Ok then, question in regards to something else related to this. If a magical effect would require a target hit by this attack to make a Fort Save in order to avoid having an ability penalty being subjected to the Target's Strength or Dexterity, would that apply to Undead or Constructs, and if not, aside from changing the effect to be a Will save, how would I be able to word the effect to actually work on undead or constructs? I'm still trying to work out the kinks on what kind of syntax I should be using for things like this.

Either make it also affect objects, which would be weird, or just say it specifically works on undead. Specific rules have a higher precedence than general ones.
