Warhammer 40,000: Rogue Trader is Owlcat Games' CRPG set in the grimdark far future where you play as a Rogue Trader — one of the few individuals with a warrant to explore, trade, and conquer beyond the Imperium's borders. The game features deep turn-based tactical combat, a conviction system (Dogmatic/Iconoclast/Heretical) that shapes your story, companion loyalty mechanics, and colony management across the Koronus Expanse. As a 40K RPG, it's the most authentic tabletop experience in video game form.
Picking the right build determines how your experience plays out. These builds are ranked by overall effectiveness — factoring in damage, survivability, gear requirements, and how well they scale into endgame.

Gearing Tips
- Invest in your primary equipment first — it gives the biggest power spike
- Companion approval affects story endings significantly. Pay attention to companion reactions to your decisions — some companions approve of opposite things.
- Psykers are the strongest damage dealers but Perils of the Warp can cause friendly fire. Position Psykers away from allies and manage their Warp instability meter.
- Don't spread upgrade resources across multiple builds until endgame
