Dragon Age: Inquisition · Class specialization
Rogue specializations
Assassin, Tempest, and Artificer are the three Rogue specializations named in the guide; it says specializations unlock further into the game.
How it works
The guide lists Assassin, Tempest, and Artificer under Rogue specializations and says additional specializations unlock further into the game. It describes specialized Rogues broadly as able to master assassination, traps, or destructive alchemy, but does not assign those functions to a specific specialization or provide ability effects, upgrades, or unlock conditions.
