Well the combat is still ongoing. At first i thought the DM was going to use my PC's stats with dread wraith adjustments and abilities, but now i think hes just using the standard CR11 dread wraith against a party of ECL 15.
At this point im pretty sure the DM is trying to say "Solve the puzzles in the correct manner or die."
He did however say that i can get resurrected or raised once the combat is over.
I am interested to know how that is going to happen, as adventuring parties dont tend to lug around a few thousand grand worth of material components for raise dead or similar spells, they can get free loot from my corpse, and we are in a evil, pocket dimension, where evidently the usual rules do not apply(such as turning being less effective than it may be), so it does not seem a stretch to me for him to say "You try to bring PC X's spirit back but something appears to be interfering with your attempt.".
Even if i was instantly resurrected at the end of the combat without the party having to pay for anything the -1 level is going to suck, all because i wanted to check the corpse a bit more.
For the record the will save was at least DC 34, as i got a 33, and still failed.
