Last updated 17 October 2015: Added the location Perilous Cave Level 2 for Tusked Bogan, removed the location Perilous Cave Level 2 for Maggot Brood.

Goal:	Kill all 29 champions (blue enemies) on the list.
Category:	Stamp the Champs: Challenges, Act V No Time for Losers: Hardcore, Act V

Below, I've listed all enemies needed for the achievement(s) and where to find them. If I discover more locations, the list will get revised. Please note that all enemies have been found while playing in Adventure Mode.

Two of the champions on the list differ a bit from the remaining champions: Executioner and Revenant Archer. You'll find a section about each of these enemies below the list.

Executioner

Champion Executioners should, compared to their normal and rare counterparts, spawn in Pandemonium Fortress but for some reason they don't - at least, I have never been able to find them there. Fortunately, they may still spawn in nephalem rifts.

Revenant Archer

Before patch 2.2.0, champion Revenant Archers could only be found after opening a certain Resplendent Chest in Westmarch Commons (displayed in the video). With the release of patch 2.2.0, champion Revenant Archers can now be found "the usual way" in both Westmarch Commons and Westmarch Heights.

The event displayed in the video can still be found and it still spawns a group of champion Revenant Archers but it is no longer the only way to find this champion enemy.
