If there are secrets to be uncovered or a mystery to be solved, there are none more adept than an Investigator. Experts who have honed the skills of observation and deduction to heights which rival even potent divination magic. For an Investigator, the only thing that stands between them and the truth is time.
Eye for Detail
3rd-level Investigator Archetype feature
Your perceptive abilities are a finely honed tool. You can make Intelligence (Insight) and Intelligence (Perception) checks.
You can also use your Cunning Action to take the Search action as a bonus action on your turn. Whenever you take the Search action, you gain additional information as if you spent 10 minutes investigating the focus of your Search.
Investigator Exploits
3rd-level Investigator Archetype feature
You learn certain Devious Exploits at the Rogue levels noted in the table below. These don’t count against your total number of Exploits Known and can’t be switched upon gaining a level.
| Rogue Level | Exploit |
|---|---|
| 3rd | inquisitive eye, precision strike |
| 5th | exposing strike, survey dungeon |
| 9th | survey settlement |
Predictive Fighting
3rd-level Investigator Archetype feature
You observe your enemy’s combat tactics to better predict openings in its defenses. You can take the Search action, focusing on a creature that you can see within 60 feet (DC = 8 + its Challenge Rating). On a success, for the next minute, you can add your Intelligence modifier (a minimum of +1) to weapon attack rolls against that target and you do not need advantage on your attack roll to add your Sneak Attack bonus damage.
If you attempt to use this feature on another target, this bonus ends for any previous targets.
Insightful Strike
7th-level Investigator Archetype feature
Your predictive capabilities in combat have increased. Each time you hit a creature with an attack that adds your Sneak Attack bonus damage, you can use Cunning Strike feature to reduce the bonus damage by 1d6 and learn one of the following characteristics of your choice:
| Armor Class | Highest Ability Score |
|---|---|
| Condition Immunities | Lowest Ability Score |
| Damage Resistances & Immunities | One Special Feature (Spellcasting, Exploits, etc.) |
In addition, if you use Predictive Fighting to take the Search action, you have advantage on your ability check if you have hit the target with an attack since the end of your previous long rest.
Adept Investigator
13th-level Investigator Archetype feature
Your investigative process leaves no stone unturned. Using the survey dungeon or survey settlement Exploit takes you half as much time and you gain twice as much information.
Also, whenever you finish a long rest in a settlement, or a short rest in a dungeon, you gain the benefits of the survey settlement or survey dungeon Exploit, respectively. Though, this feature does not interrupt your short or long rest.
Unerring Sight
13th-level Investigator Archetype feature
Your perceptive abilities rival those of supernatural entities. You gain Truesight to a 10-foot radius, and when you observe anything within that radius you have advantage on all Insight, Investigation, and Perception checks.
As you gain levels in this class, the radius of this Truesight grows to match the radius of your Blindsense feature.
Exploit Weakness
17th-level Investigator Archetype feature
You perfectly exploit your foe’s vulnerabilities. When you use Predictive Fighting, you automatically succeed on the Search check, and you roll d8s, in place of d6s, for your Sneak Attack damage bonus against that creature for the duration.
