Roguish Archetype: Investigator

Clever

When on the battlefield, you use your expert obsevational skills to make swift decisions. Starting when you choose this archetype at 3rd level, you may add your intelligence modifier to AC at a maximum of 2. This will increase at 9th level, and again at 13th, and 17th. Additionally, when attempting to trip, disarm, grapple, or escape being grapped, you may use your investiagtion skill instead of athletics.

interview

At 9th level you gain the ability to learn additional things from your cunning investigations. As an action, you can attempt to interview a target of your choice and learn a number of things about them from the list below:

Armor Class

Rogue levels (if any)

One weakness of your choice (if any)

One resistance (if any)

Investigation modifier

You can learn a number of things about the target equal to the maximum AC bonus granted by your clever feature. The interview fails if the target makes a successful charisma (deception) check (DC = 8 + your investigation skill). The target makes this check with advantage if either of you are in combat and makes it at disadvantage if you have observed it for ten minutes or more before choosing to interview. Once you use this feature, you cannot do so again until you have finished a long rest.

Renowned Detective

At 13th level, you are a detective of a very high merit and the mere sight of you throws criminals off of their game. All creatures who have broken the law within eight hours in the eyes of the location's ruling law have disadvantage on all deception checks against you. Additionally, you have advantage on all persuasion checks made against local authorities.

Keen Observer

At 17th level, nothing gets by you. You now may add double proficiency to your investigation checks and if you already add double proficiency, you may add your proficiency bonus a third time. additionally, when you roll your sneak attack dice, and total is less than your investigation skill, you may choose to use that instead.
