Specializations are sub-class choices that further define and customize characters. Companions gain theirs the first time they are loaded as a party member after the Inquisition reaches Skyhold, while the Inquisitor can learn theirs by inviting trainers from the war table to teach them their specialization. The Inquisitor can only learn one specialization. Specializations will be unlocked after the first set of repairs is made to Skyhold, when the war table operation Specializations for the Inquisitor becomes available. You need to use Cullen if you are a warrior, Josephine if you are a mage or Leliana if you are a rogue to complete the operation. The trainers will then be available at Skyhold. Only after a specific quest, they are not an automatic feature of Skyhold.
These mages specialize in binding the spirits that are drawn to death. They can put the fear of death into enemies, bring spirits to fight on their behalf and even cause devastating explosions when their enemies die.
Intricate mechanisms are the core of the artificer’s craft: Deadly traps; Distracting contraptions; Marvels of engineering turned to deadly purpose. If an artificer is standing at the far end of a seemingly innocuous stretch of the battlefield, you should find another path. If he or she is smiling? Best just to hope your affairs are in order.
Any rogue can kill a target, but assassins make death into an art form. They specialize in quick, deadly kills that let them slide back into the shadows undetected, or indirect kills that eliminate targets while the assassin is safely away.
Champions are defenders and protectors, and when a warrior trains in the champion’s tradition, they become unstoppable. Champions use their armor, weapon and awareness to shrug off incoming attacks while holding critical positions on the battlefield and protecting allies in the process.
Companions are locked into one specific specialization, which is not unique to them. There are some discrepancies between companions' gameplay specializations and their stated role, such as Cassandra having the Templar specialization despite being a Seeker.
While the Inquisitor's chosen specialization isn't unique to them, players can still attain variety in function by having the Inquisitor use the specialization differently from the companion, either by distributing ability points differently or having completely different set of Class ability to synergize with, for example having Blackwall developed as a complete tank by having his Champion abilities boosted by the Vanguard tree, while the Inquisitor can take a more balanced role by having points invested in weapon abilities while the Champion specialization serves as a supplementary upgrade in choking and taunting tactics. The TrespasserDLC adds alternative upgrades to abilities that can help the player further explore how playable characters can best function with each specialization.
