How many times is this leadership action allowed to be used per Kingdom turn? It’s in the Companion’s guide. It seems really powerful to let every leader use it once per Kingdom turn. Was it intended to only be used once per Kingdom turn total? Or intended for every leader to be able to use it once (so 5 times per Kingdom turn for a party of 5).
First, Harrim needs to be Magister (according to the book).
That means that the players not only need to refrain killing or silencing his neverending rambling about the inevitable end of times, but give him an actual leadership role in their kingdom!Jokes aside, the Folklore skill is not a good one, so passed level 5-6 the test should be harder if they don't invest in it.
Personnally, I think it's strong without being broken: the Linzi one is overused by my players and it is also quite good (-1d6 unrest on a success if I recall).
They don't have a ton of unrest so they never felt the need to spam it though.
My players are trained in folklore. I homebrewed it a little bit. If Harrim is the magister, the players can do it once per kingdom turn and it doesn't take one of their leadership actions to do it. It's just a side benefit of him being magister. That applies to all leadership NPCs. I think that's a good benefit for having an NPC be in a leadership role without letting them spam a powerful ability.
