Decisive

Adept at finding the truth in investigations, seeing the weaknesses in the things people want to hide, and aiding in others in combat

Master of Intrigue

When you choose this archetype at 3rd level, you gain proficiency with the disguise kit, or the forgery kit, and one gaming set of your choice. You also learn one language of your choice.

Additionally, you can unerringly mimic the speech patterns and accent of a creature that you hear speak for at least 1 minute, enabling you to pass yourself off as a native speaker of a particular land, provided that you know the language

Tactician

Starting at 3rd level, you can use the Help action as a bonus action. Additionally, when you use the Help action to aid an ally in attacking a creature, the target of that attack can be within 30 feet of you, rather than within 5 feet of you, if the target can see or hear you.

Decisive Fighting

At 9th level, you gain the ability to decipher an opponent’s tactics and develop a counter to them. As a bonus action, you can make a Wisdom (Insight) check against a creature you can see that isn’t incapacitated, contested by the target’s Charisma (Deception) check. If you succeed, you can use your Sneak Attack against that target even if you don’t have advantage on the attack roll, but not if you have disadvantage on it. As well you gain advantage on attacks of opportunity against the creature.

This benefit lasts for 1 minute or until you successfully use this feature against a different target.

Unerring Eye

Beginning at 13th level, your senses are almost impossible to foil. As an action, you sense the presence of illusions, shapechangers not in their original form, and other magic designed to deceive the senses within 30 feet of you, provided you aren’t blinded or deafened. You sense that an effect is attempting to trick you, but you gain no insight into what is hidden or into its true nature.

You can use this feature a number of times equal to your Wisdom modifier (minimum of once), and you regain all expended uses of it when you finish a long rest.

Soul Of Deceit

Starting at 17th level, your thoughts can’t be read by telepathy or other means, unless you allow it. You can present false thoughts by succeeding on a Charisma (Deception) check contested by the mind reader’s Wisdom (Insight) check.

Additionally, no matter what you say, magic that would determine if you are telling the truth indicates you are being truthful if you so choose, and you can’t be compelled to tell the truth by magic.

The Missing Scale

At 17th level, you further learn to exploit a creature’s weaknesses. While your Insightful Fighting feature applies to a creature, your Sneak Attack damage against that creature increases by 2d6.
