Solace

Bring peace to the Grey Mourner. She lives in the Resting Grounds and asks you to carry a Delicate Flower to a grave in the Queen's Gardens. The catch: taking any damage - a hit, a hazard, even resting at a bench or riding a Stag - shatters the flower, and you have to fetch a fresh one from her. So plan a clean, careful route from her to the grave (near where you fight Execution) with no combat and no benches. Deliver it intact and this pops. Fiddly, but not combat-hard.
