They can also easily be cumulative if required, something that Boon/Bane does not currently allow.
and I think that is one of the main reasons for the bane/boon. To keep accumulating DMs which push a roll "out of bounds".
For example you are jumping across a gap. -DM for night, -DM for rain, -DM for carrying a load, -DM for being shot at while climbing...
It's one thing to make success harder, and another to make the roll unnecessary because it is now impossible because of all the accumulated DMs.
Do I personally think this is a problem that needs a new mechanic to solve? No. It shouldn't happen too often and if I saw that the task with DMs was getting beyond reason, I could always adjust the difficulty to bring it where I think it should be.
Overall though, here are my thoughts
Based on my initial understanding, I think it currently is not written well enough.
Through discussion in the forums, I have a better understanding of why and when to use it.
I would rather have it gone and use something like what Wizard suggests above, rather than be left written
as is.
I'm not against bane/boon if it is written up well so that people are clear on not just how, but why and when to use it.
No, I am not going to try suggesting the exact wording for the rules because I still don't have a 100% grasp on how I'm going to implement it let alone want to tell others how to.
