The ambitious Bandit I

So this prophecy on cruel difficulty is bugged.

I wasted 2 hours full clearing the chambers of sins level 1, the dread thicket, the northern forest and the crypt over and over again and still nothing happened. That shouldn't be the case.

In the end i gave up on that and just left it as a wasted prophecy slot because sealing it would waste 7 SILVER COINS!...
