Dragon Age: Inquisition came out in November of 2014, but the final DLC wasn't released until almost a full year later, in September of 2015. In the time between the game's release and Trespasser's, several DLCs (downloadable content) were released for the game.
While it wasn't as many as players have received for past games, they were still substantial additions to an already massive game. Now, all these years later, we're ranking the significant expansions (not the preorder bonuses or item packs) from worst to best.
5 Dragonslayer
The Dragonslayer DLC was a free addition to Dragon Age: Inquisition's multiplayer mode.
The multiplayer function was ignored by most of the game's players. Many fans took it further, criticizing EA for forcing BioWare to add a multiplayer mode in (what they considered to be) an attempt to extend the game's life and earn money from microtransactions. As a result, Dragonslayer must appear at the bottom of this list.
However, there were some upsides if you happened to be one of the few gamers who enjoyed multiplayer. This DLC was, as mentioned previously, completely free, and came with new armour and new characters to play - including Isabela, a companion from the second game! It also added a new game type, in which players fought High Dragons in special maps.
4 The Black Emporium
The Black Emporium was first introduced as DLC in Dragon Age 2. It was a simple addition that allowed players to buy unique and powerful items and access a mirror that let them change their appearance. Unsurprisingly, it was a hit!
It returned for Dragon Age Inquisition, then, with updated graphics and brand new items. Fans love to point out that the red-lyrium infused corpse of Meredith, the final boss of the second game, can be found there. This is a simple and clean DLC that is a nice addition to the game; it only appears so low on the list because of its size relative to the main expansions.
3 The Descent
The Descent was one of three major DLCs for Dragon Age: Inquisition, all of which added a whole new map, a new story, and new character interactions.
The Descent takes place underground in the Deep Roads as you strive to find the source of unnaturally common earthquakes in the Storm Coast. You journey with a Shaper, Valta, and a member of the Legion of the Dead, Renn. It's unique for focusing so heavily on Dwarven lore, history, and mythology - they're a race who have been criminally underused during the rest of the games. As a result of this, many players who love dwarves would cite this as their favourite expansion.
However, other players weren't as thrilled by The Descent. The new map is entirely underground in the deep roads, chunked into descending levels. Unfortunately, the walls of the Deep Roads aren't interesting to look at over and over and over again, so the questing didn't capture some players' attention. While it gets more varied towards the end of the expansion, this flaw leads to its lower place on this list.
2 Jaws of Hakkon
The Jaws of Hakkon was another of the three major DLCs for this game.
It takes place in a brand-new, above-ground map called Frostback Basin, nestled in the mountains between Ferelden and Orlais. The Avvar live in this region; they're related to humans, but the Avvar's ancient human ancestors chose to adapt to the cold, harsh environment in the mountains. Over time, they evolved particular traits that make them unique as a species, separate from the rest of humanity. As you quest in the Frostback Basin, you're following the tracks of the Inquisitor before you, the one who led the original Inquisition around the time that the Chantry was founded. In addition, you spend some time getting to know the Avvar and setting up diplomatic relations.
This DLC was much more open-ended than The Descent was, allowing players to explore this new map freely, rather than in levels. In addition, they expand in detail on the fascinating Avvar culture, a race that isn't even playable in any Dragon Age game so far. It also just feels more connected to the main plot of the game, since you're investigating the previous Inquisition. All-in-all, Jaws of Hakkon is definitely worthwhile.
1 Trespasser
Trespasser is a polarizing DLC, to say the least. It takes place several years after the events of the main game have concluded and explains to the players why Solas disappeared after the final boss battle.
To start, its mere existence was polarizing. Some players were happy to get some answers in the short form. Others complained that the game's "true ending" shouldn't be hidden behind a paywall (something that's been done before by Bioware, in Dragon Age: Origins).
Then, you get to the plotline. Solas does a lot of monologuing to explain things about the ancient elven "gods" before he finally tells you his master plan to tear down the Veil (the thing that separates the magical world and the physical one) and restore what the elven species lost. Some players saw Solas as a madman. Others sympathized but thought that he needed to work together on a more sensible plan. Still others didn't think he was in the wrong at all - indeed, they wanted to join him.
Whether you are angry at BioWare for putting these explanations behind a paywall, regardless of how you feel about the story, Trespasser is bound to be an emotional experience. You get to see how your companions are doing after they've left the Inquisition (or stayed). You'll get to talk to the new Divine. You get to explore the Winter Palace again. You'll get to have one last romantic moment with your sweetheart.
All this - and more - earns Trespasser the number one spot on this list.
