At Skywatch. My team and I were all still pretty low level and we found that little thin hidden ledge that has a cave set into it that was home to a Hallowed Knight that was too powerful for us to kill (it's health read "?????"). But we were too determined to get into the cave and find out what was inside. So began out bait and switch where one of us would approach from one side of the ledge and draw the knight out while the other ran into the cave. Lots of laughs and girly screams were heard and many deaths and respawns were needed. We eventually found a dead ghost inside. It was worth it.
