Achievements or trophies mark specific accomplishments made during all playthroughs of Dragon Age: Inquisition. These include finishing plot-related activities, making specific choices at certain key points in the game, crafting choices, and performing certain tasks and meeting certain individuals. Each milestone also awards the player a certain number of points. Achievements are viewable from the Origin application, under my games, and right-clicking on Dragon Age: Inquisition.
Destroy all the Winter Shards and light all the fires in the Old Temple. The three Winter Shards spawned by Gurd during the fight with him has to be aquired during that fight (don't kill him too quick because then all shards will not be spawned)). The other shards and camp fires can be collected by returning to the temple later on.
Demonslayer, Pathfinder, and On Burning Wings may not unlock on every playthrough. The first, even if demons are farmed. The second, even if all or just one camp is established per area. The third, more likely to happen if Morrigan drinks.
