Rise of the Ronin has several different weapon types, from melee to ranged, but only the former can use Combat Styles. These provide Martial Skills used when holding down R1 and pressing a face button on the DualSense.
Several Combat Styles exist, though you need to unlock them over time. Some are unlocked by forming Bonds with allies, while defeating Fugitives, mini-boss-like enemies in each region, grants access to others. In several cases, you can unlock the same Combat Style from defeating a Fugitive as you would from forming a Bond.
Enhancing a Combat Style requires increasing your Bond with the corresponding ally who taught it and training to achieve a higher rating. This will unlock further Martial Skills for that Style.
If you forget the corresponding ally, go to the Combat Style tab in the main menu, select the weapon type and then the Style in question. Here’s how to unlock all Combat Styles in the game.
