Every large public dungeon in ESO includes a group challenge, which yields a skill point for completion. Achievement hunters will no doubt want to kill all of the public dungeon bosses / champions for extra achievement points before leaving the dungeon as well. Large public dungeons of course also have a skyshard in them, which at times can be difficult to find or get to.
This guide provides a map of all large public dungeons in ESO, marked with group challenge, champion and skyshard locations.
Black = Group Challenge
Red = Dungeon Champion
Blue = Public Dungeon Skyshard
Every zone has a large public dungeon. Whilst many of these can be cleared on your own with the correct build and gear, they are much more difficult to take on solo than the smaller public dungeons. What sets the large public dungeons apart from the small ones — apart from the fact that these dungeons have much more enemies in them — are group challenges, and a greater number of dungeon champions, who are named dungeon bosses and a part of public dungeon achievements.

Public Dungeon Group Challenges & Conqueror Achievements
Group Challenges are events which take place in large public dungeons. These are difficult to solo, and reward a skill point for completing them. Every public dungeon is unique, and so are the group challenges. Once you know where the group challenge is located in the dungeon, you usually find a way to begin the group challenge. Sometimes you have to light braziers, douse torches, read a specific book and so on.
It should be noted that some of the group challenges are actually bugged, and do not reward a skill point. Hopefully we’ll be able to get the skill points retroactively when this gets fixed.
Finishing a public dungeon Group Challenge gives 50 achievement points.
Conqueror Achievements are awarded for those who defeat every single named boss within the public dungeon. A smaller version of the Conqueror achievement is the Slayer/Vanquisher achievement, which requires you to kill three of the dungeon bosses in a public dungeon. The number of champions in the public dungeon varies.
If you don’t seem to be able to advance in the conqueror achievements, you should know that some of the public dungeons require you to get the killing blow on the boss for it to count towards the achievement. I’m not sure if this is intended, but that’s how it works right now.
Finishing a Conqueror achievement gives 50 achievement points.
