Inquisitive Revised 2024

Credit to Agilemind and Stabbey_TC which inspired (or I straight-up copy pasted) some abilities who I then edited slightly to fit the view I had.

Careful Cognition

At 3rd level, you gain the ability to swiftly take in your surroundings and temporarily heighten your senses and analytical abilities.

You can use a Bonus Action to take the Search or Study action. In addition, you can give yourself advantage on these checks provided you are proficient with them, you can do this a number of times equal to your proficiency modifier. You regain all uses after a Long Rest.

Scrutinize Opponent

At 3rd level, you can use a Bonus Action to scrutinize your opponent.

Choose one creature within 60 ft of you that you can see, the target must make a Charisma saving throw (DC 8 + Your Proficiency Bonus + Your Wisdom modifier) on a failure you can use your Sneak Attack on any attack you make that targets that creature, you still can only use your Sneak Attack once per turn. In addition, you may also spend a use of your Careful Cognition feature to give the target disadvantage on the saving throw.

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

Insightful Fighting

At 9th level, thanks to your analytical gaze you know how to attack a foe at the exact right moment and even make them vulnerable for a powerful follow-up attack.

Creatures now have disadvantage on your Cunning Strike saving throws provided they are effected by your Scrutinize Opponent feature.

In addition, you gain the following Cunning Strike option.

Exploit Weakness (Cost: 2d6). The damage you deal with this attack cannot be reduced by any damage resistances, the creature must make a Constitution saving throw. On a failed save, they have Vulnerability to the next attack which deals Piercing, Bludgeoning, or Slashing damage before the end of your next turn. If the creature has resistance to those damage types, the vulnerability and resistance cancel each other out for that single attack. This Cunning Strike option has no effect on a creature which is completely immune to the type of damage dealt.

Flawless Deduction

At 13th level, you can push your keen senses to the limit in order to deduce the truth about illusions and creatures through simple observation.

For 10 minutes, you gain Truesight with a range of 60 feet. You can use this feature a number of times up to your proficiency modifier, you regain all uses after a Long Rest.

In addition, when you take the Study action, you can use a Wisdom (Perception) or Wisdom (Insight) check in place of the normal check you would make if you can see what you are studying.

Unerring Focus

At 17th level, you can exploit your enemy's weaknesses more accurately and recovering from the strain of utilizing your cognitive abilities becomes far easier.

When you apply your Sneak Attack against a target under the effect of your Scrutinize Opponent feature it deals an extra 3d6 damage.

In addition, you now also recover all uses of your Careful Cognition feature on a Short Rest.
