Well, if I may, an example loosely inspired by (part of) the journey we took to get something done in that Ironsworn game. Might goof up some details, it's been a hot minute.
Abraxus (my char), Magnus, Alvis (pronounced "all-vis"!), and Harald are Ironsworn--Viking-inspired, oath-swearing iron-age adventurers--trekking to prove our sincerity to a nearby Elf circle (=village). Elves and humans had become allies when the humans first arrived, three generations ago, but those connections lapsed, the Elves kept to themselves, and other than the one exiled elf in our circle, none have been seen for a full generation. But bad stuff is going down, the necromantic dragon Dunstaad has returned from his banishment/flight, and the winters have been unusually harsh, so we could really benefit from rebuilding our connection to the Elves. Hence, we trekked out to see them, talked with them about some stuff, and each Swore an Iron Vow (slightly different oaths each, rather than one single group Oath)--but we got lots of middling successes, which means we had to prove our intentions or the like.
The elves asked us to go deal with some corrupting influences, more or less, to prove our sincerity for the bigger tasks ahead. This included, eventually, dealing with some powerful, probably at least part-supernatural bears that were making it harder for the elves to forage, hunt, farm, etc. and generally disrupting nature in the area. But we got some bad/middling rolls along the way, which bumped up the challenge. At first, we thought it would be just one bear, but we learned no--it was two bears. And then we learned, even worse, it's a mated pair...and they have cubs. Not quite full-grown, but getting there. Between all those things, that meant when battle was finally joined, the two sides were much closer to evenly matched--and thus the difficulty was (IIRC) 3 or 4 rather than the 1 it would've been to hunt just a single bear.
