@Manbearcat the three examples:
Undertake a Perilous Journey
The party was needing to travel 5 days through the cavernous tunnels that linked the last bastion of the subterranean dwarven empire, Darrowhold, to the ancient and abandoned ancestral crypt. The cleric took the roll of the trailblazer and succeeded with a 10+. The barbarian took the roll of the scout and got a 7-9. The fighter was the quartermaster and failed with a 1-6.
The cleric got them to the crypt in 5 days. When the barbarian got them to the crypt, he lead them right into a mining operation with a dozen derro - because it wasn't a hard failure I said that it wasn't an ambush, just a straight up fight. The quartermaster who failed ended up getting his pack caught on a stalagmite, ripping open the bag, and having half their food spill into a pool of water, ruining it. Luckily, the group over-prepared so they would still have enough food as long as they didn't linger in their exploration of the crypt or get lost on the way back.
Parley
Most of the time the group wants to parley, it's actually a Charisma Defy Danger as they are just trying to sweet talk a guard with nothing to offer. A recent case was the group sought out the dwarven thane to request a runesmith to accompany them back to their home city to repair a situation. They offered a pact between the home city and the dwarves, but got a 7-9 result. The thane said that he would agree to their offer, only after the party recovered an heirloom treasure from the ancestral crypts (see above).
Combat
This is one of the most recent and egregious examples. (It's been a couple weeks, so I'll try to remember everything.) The party was exploring the crypt and found in the central chamber was a pile of bones and there was an invisible lich standing nearby. The group had heard of a skeletal dragon in the area, so the cleric cast True Seeing and instantly saw the lich. The bones animated and became a dragonbone.
Barbarian charges and demolishes the dragonbone in two rounds, rolling so well the dragonbone doesn't get a chance to do a move on him. (Like getting a 12 and a 13). But even if it did, the fighter had a defend action to soften the blows on the barbarian.
The lich calls forth a horde of ravenous ghouls. Cleric turns undead with a 10+. All the ghouls run away, lich is dazed. Something happens (I forget what) to make the lich visible - maybe the dust from the dragonbone is thrown over it or something. Fighter and Barbarian can see the lich now. They hack him to pieces before he gets an attack.
No one ever rolls poorly enough for me to get a DM move. Or if they do, they have powers to "turn danger against itself."
