For the Living Trophy in Ghost of Yōtei

There are 22 Yotei Six camps. Not every red camp on the map counts. The ones that do show a reward in gold text, usually a new technique, when you select them on the map. Clear every enemy, including the leader behind a locked gate in some camps. You then arrive at the camp's Altar of Reflection: pray there (swipe down on Touchpad) before you leave, because the camp counts only then.
