I am right now running (play by post viewtopic.php?p=36056#p36056) Tower of Salt and there are strong chances that, during the various trials in the Tower of Salt, there will be a total party kill.
The trials in the Tower of Salt can be very tough and the text of the adventure itself provides you a way to bring back to life some characters that died in the dimension where the trials are run. However, the adventure doesn't say what you shall do if all characters die and the trials are not all completed.
This adventure is part of a campaign, so if this adventure is a failure and a TPK (including Sulla?), then follow up adventures of the Saga of Hadeen may not become available to play (especially if Sulla dies as well).
What do you think is the right solution?

I'm not leaning towards letting the characters die in the parallel dimension, if so the dice dictates, and then they will see Sulla letting himself be cut down (his remit in this trial dimension was to let his allies fight on his behalf and wasn't allow to do anything at all, not even speaking or making gestures).
Ultimately, the test will be perceived to be about Sulla staying true to his remit, even if it means not reacting while you are getting killed.
Maybe... :roll:

Eventually, the characters *almost* managed to overcome the third and last trial, but they were a bit unlucky and ended up in a TPK in the parallel dimension of the trial.
Sulla kept his word and didn't take any action, even when the third monster, slowly and painfully, killed him.
For the fact that he kept his word unti the very end, Yoosef decided to honour Sulla and his companions by letting them out of the Tower of Salt and continue their quest to understand the will of the deities about Sulla.
