Those who pick up the methods of the adaptable duelist learn to use their training to fit their every need during a fight, changing fighting styles to best put them in an advantageous position so that they strike true.

Roguish styles

When you start your path as an adaptable duelist you learn the styles that take the form of the fighting styles that are often taken by other who use a more, traditional fighting style. you gain access to the Dueling, Two-weapon fighting, finesse fighting, defense and archery fighting styles, you can only have one of the fighting styles active at once and can change styles as a bonus action. You also gain a new way to use your sneak attack feature, you no longer need advantage on your attack if the attack you are using is benefitting from your current fighting style, other than the finesse fighting style (Melee attack for dueling, ranged for archery, either for two-weapon fighting,).   

Riposte

Starting at level 9, you are able to use your opponents momentum against them, when you use your uncanny dodge feature, you can make one attack against the person who triggered your uncanny dodge. If this attack lands and applies sneak attack, you half your sneak attack dice (rounded up).

Improved roguish styles

By the time you have reached level 13, your abilities to use your styles gets much more powerful, to the point where you can have two of them active at once and it no longer takes a bonus action to change a stance you can however only change one stance per turn. your ability to change weapons to adapt has also improved, you can draw and stow double the amount of weapons that you normally would be able to.

Master Duelist

Once you have reached level 17 your abilities are truly unmatched. You gain an additional  reaction, you may only use one reaction per trigger, and you can only use the second reaction to make an opportunity attack, or to use your uncanny dodge feature. (I.E if you get hit once, you may only use one reaction to uncanny dodge but if you get hit on the same turn you may use another reaction to uncanny dodge again.). each of your fighting styles also gain the following additional benefits.

• Dueling: You gain advantage on your attack rolls with melee weapon attacks if you are the only person within 5 feet of the target and no one is within 5 feet of you.
• Archery: your ranged attacks now crit on a 19-20, 18-20 if you have advantage on your attack roll.
• Two-weapon fighting: you can apply sneak attack an additional time as long as the second trigger of your sneak attack comes from your off-hand weapon.
• Finesse fighting: Your AC increases by 1. You also can take a -5 to hit with a finesse melee weapon and if the attack still hits, you can reroll up to half your sneak attack dice.
• Defense: When you are hit by an attack and use your uncanny dodge feature, the next time you take an attack you can add your dex mod again to your AC.
