Investigator (Intelligence) (5A)

This is an original Exemplar subclass for 5A.

When his manservant was questioned we were told that the Duke had arrived at sundown yet all signs indicated that he died hours earlier. This would suggest a shapechanger or possibly an illusion masquerading as the duke, making the Duke’s son—a known mage—a possible suspect. However when speaking with the servant I noticed something peculiar: he spoke the local dialect, yet his idioms suggest he comes from Ophar. Far be it from me to judge someone based on their origin, but Ophar is infamous for cults of the Abyssal Lords. Add into that the slight yellowing of his hand from the use of sulfur, his curious aversion to our cleric, and it became clear he was a demonologist. A mystery solved but not the last—for he is not the murderer!

Investigators are exemplars of the notion that knowledge is power. They use their cunning to aid in endeavors—sometimes by solving mysteries and other times more militantly as they help allies to find a foe’s weaknesses. They have a sharp eye and a background that lets them assemble clues into a picture of events and who did what.

An investigator might be called a detective, sleuth, magistrate, inquisitor, bounty hunter, or truth-sayer.

1st Level: Focus Ability

Your Focus Ability is Intelligence. You are proficient with Intelligence and Wisdom saving throws.

1st Level: Investigator Proficiencies

When you choose this aptitude at 1st level, you gain proficiency with Insight, Investigation, and thieves’ tools. You gain expertise (double Proficiency Bonus) in Investigation.

2nd level: Investigator Tricks

These tricks are only available to Investigators.

Analyze Move. When an enemy within 30 feet hits with an attack, you can force that opponent to re-roll and accept the second result.
Exploit Opening. When an ally attacks a creature in your reach, you can make a melee attack with advantage against that same creature.
Find Weakness. Use this trick at any time. Select a creature within 30 feet. You learn it's Armor Class and any damage vulnerabilities, damage resistances, damage immunities, and condition immunities the creature has, as well as identifying which of its saving throws is the worst.
Preempt. When another creature is about to take its turn, you can use this trick as a reaction to take an action, including movement. This occurs outside your turn; you cannot take a bonus action and you do not recover your reaction or the ability to use a trick.

3rd Level: Lethal Comeback

At 3rd level, after an opponent makes an attack against you or causes you to make a saving throw, you can use a reaction to attack that opponent with advantage on your attack roll.

6th Level: Investigation Dice

At 6th level, when observing a creature, you can spend an Exemplar Die and learn information about the target. You always learn what languages the target speaks (if any), what items they are carrying, what natural attack they can use, and what armor they are wearing. In addition roll a Exemplar Die and learn additional information as given below.

The target’s alignment.
If the target is disguised or capable of changing their form or appearance
If the target has spells or magical abilities. Also and what spells the target is under (if any).
What skills the target is proficient in.
The target's point of origin, native terrain, and the approximate location (within 1 mile) they have spent most of their time in the last three days.
On a result of six or more, you get to chose what information you learn.

If there is no information of the relevant type to reveal, you can reroll the Exemplar Die, but the second result is final.

In addition, your skill and breadth of knowledge allows you to see the commonalities of all languages. You can translate any language, even one you have never heard of. Spend an action and roll a Exemplar Die to translate a number of pages of text or rounds of speech equal to the result of the Exemplar Die. If you do this during a long or short rest, you translate ten times as much.

6th Level: Sucker Punch

At 6th level, when you have advantage on an attack roll and hit, you can add your Exemplar Die to the damage. This does not spend a die from your Exemplar Dice pool.

10th Level: Investigating the Scene

At 10th level, you can spend a Exemplar Die and learn information about the location you are in, up to 100 feet in radius. You always learn this information:

What this place is normally used for and what kind of people frequents it.
If an attack was made or a spell was cast in the last three days, you know that this happened but not what specific spell, attack, perpetrator, or target.

In addition, roll a Exemplar Die and learn the corresponding information, below. You learn the described information and when these events happened.

A brief description of all significant events in the last three days.
The three highest-level spells cast in the last three days.
Weapons attacks made here in the last three days.
General description of creatures who visited in the last three days. If you are acquainted with these creatures, you identify them.
A piece of or personal item from a significant creature who visited the location in the last three days. Useful for divination spells and as physical evidence.
Identify a creature that frequents the area and can be a possible witness.
You spot any hidden construction, secret doors, hidden caches, and traps, even those who have been discharged or destroyed. You also learn when these things were used or triggered.
On a result of eight or more, you get to chose what information you learn.

If there is no information of the relevant type to reveal, you can reroll the Exemplar Die, but the second result is final.
