Topic: Death Frost Doom question
I'm getting ready to run DFD for the second time. In re-reading the adventure there are several references to the undead in the greater tombs that have me a little confused. There are descriptions for both whether or not the dead have risen and I want to be certain I'm not missing something.
As far as I can tell there are 3 ways to gain entrance to the greater tombs.
1) Kill the Plant Creature
2) Use 'Speak with Plants' to convince it to let you pass.
3) Miraculously find the escape hatch.
All but the first method go against normal use of this location. Are the dual descriptions in the greater tombs specifically to address these two highly improbable possibilities? Or is there another way to gain entrance that I didn't consider?
