No.Did the GM decide beforehand what the runes would show?
Here is the post:You stated it in your example the first time you posted it.
That doesn't say that on a failure they would have been incapacitated. It just described some possibilities, by general reference to how MHRP/Cortex+ Heroic works. One possibility would be stepping up the complication.the PCs had been teleported deep into the dungeon by a Crypt Thing (mechanically, when the PCs confronted the Crypt Thing the Doom Pool had grown to 2d12 and so I spent it to end the scene), and all were subject to a Lost in the Dungeon complication. As they wandered the dungeon looking for a way out, I described them coming into a large room with weird runes/carvings on the wall. One of the players (as his PC) guessed that these carvings might show a way out of the dungeon, and made a check to reduce/eliminate the complication. The check succeeded, and this established that his guess was correct. (Had it failed, some further complication might have been inflicted, or maybe the carvings were really a Symbol of Hopelessness, and the complication could have been stepped up to a level that renders the PC incapacitated.)
As I said, I don't (and didn't) know; so you can't know.
