all Z10 (or, as i call it Z><) bosses are summoned as personal raids, the other personal raids are special, when you give their loot, along with their essence, you get a legendary item-
unfortunately you have to craft the essense first. the exception is magma horror, which gives only part of what you need for sagramesh the conqueror, and is obtained from quest bosses directly. it doesn’t require giving up the essence to get the legend
magma horror is in subterranean depths. misako essence is from vornstaag quest bosses(each drop components). Mestr Rekkr is similar, in Nordent. I believe there’s another besides z10s but cant recall what it is.
