No gold, no XP, no fame or prestige. OK.
Can't be reported at all. So if a character dies, that doesn't count either, right?
And any gold spent, items used, etc come back at the end of the scenario? If not, I think a lot of players will not be interested in risking life and loot for a one-time buff boon...
Why is there even a chronicle sheet? Oh yeah, the one-time buff boons...
I like the concept, don't get me wrong, but a few GP or a possibility of 1 fame point if handled well would certainly make it more appealing to players I think.
