Lore of Sshamaths defences, forgotten or ignored?

[Amal'launim]

I've been meaning to ask this question for some time, but it didn't get through the approval filter last I tried and I sorta forgot trying again, so here it is:

I'm Interested in knowing whether the below Epic Spell is actually functional IG or not, as I'm sure that would have pretty far reaching consequences for the playstyle down in the UD or if it's just sorta been ignored/forgotten?

Defenses
[-snip-] The most formidable of these defenses consist of epic spells that harden the stone, lock down the city in a continual Dimensional Anchor, redirect Teleport spells cast by strangers, and cause paralyzing pain to anyone within a 1 mile radius who seriously thinks about attacking the city or its citizens.

Should this bit be removed from the official lore section about the Underdark, or could we at least be provided with a fair DC to avoid this? =P *happens to know a handful of drow or more that would need to make regular saves against it*

It is a bit of both I think. That lore was copied wholesale from another site. I don't think the implementation of that particular spell would be fun, fair, or particularly interesting for players.

So, probably will not go in.

We'll just say, as is in the lore, that another one of the defenses is countering this defense. The schools are in such competetion with each other over who can make the best defensive measures they sometimes unknowingly create a defense that cancels out another defense, or sometimes creates a wholy different defense. I think this is a good explaination why your PCs won't be feeling the effects of this defense unless it was say... focused by a diviner.
