Two Questions about tangleroot

[Tulmeel]

My first Question is >>> Is it true that Wisperdoom can not be killed at the present moment?

Two>>> In one of the quests there are blade traps that rise out of the floor in the hall way followed by spike traps next to a shrine on the right. Is there a trap box for these two traps? We had some pretty good search numbers for that level quest and no body spotted or found the boxes. My Rogue found the boxes for the other traps and disabled them. We went through twice and failed there and now were else in the entire series.

It may be that I just failed to focus on the right area.
