Successful ascension would rest on the supposition that the conventional mechanics of Sgrub are still in play and applicable to us. Also, that it is indeed a genuine quest structure and not just a big rectangular rock with a red thing painted on it.

But given our current shortage of time players, it's unlikely that an occasion to experiment with the idea will present itself any time soon.
