Unfortunately, last monday night our transmuter wizardess met her early (only 160!) demise at the hands (claws) of some elf-hungry trolls.
Her transmuter stone was not on her, because another character borrowed it to get +10 movement and carry an urgent message to the king.
Now, we had to stop the session because there is a time-rift. Either the stone keeps working after her death, or it stops.
If the stone keeps working the runner will press on to the king’s location. But if the stone stopped working, the runner will go back to find the wizardess’ corpse or get in touch with her familiar and then find the corpse. And the runner has enough arcana to know that she died (there is the fact that she could’ve made another stone, but not eight hours had passed).
(…) you can spend 8 hours creating a transmuter’s stone (…) If you create a new transmuter’s stone, the previous one ceases to function.
So, after that not-so-quick exposition, once a transmuter wizard soul departs the body, do the transmuter stone keep working?
Regarding the golden rule, I’m the DM of the game, and I have no idea on how to rule the issue. So I can’t really ask the DM.
