What a great idea!
I have been playing a toned down version of ironsworn for a while and I am very glad I stumbled upon this.
Only reduction will address is the lack of progress rolls. I find the possibility of ending a quest/fight/whatever early, but at a big risk too appealing.
I'm mostly writing this above part to seem less like a pendant when saying this: the second line under "Fiendship" in the English print version has a typo.
