Tactician

A tactician studies their targets on the field of battle to better learn how to kill them. Taking advantage of every slip, hesitation, and falter as they take precise shots through the chinks in the armor.

Studied Target

Starting at third level. as a bonus action, you can designate a target you can see. That target is now treated as your favored enemy as per the ranger revised class feature(+2 to attack and damage rolls, advantage on intelligence checks against them, and advantage on survival checks to find them).

You can only have one studied target at a time, and it is a bonus action to switch studied targets.

Educated Sneak Attack

Starting at 3rd level, as a bonus action, you can choose a creature and make an Intelligence check using a relevant skill. The DC is equal to 10 + half the target’s challenge rating. If you succeed, you learn the target’s weaknesses and vulnerabilities, if any, or identify any spell the target is casting. Additionally, you have advantage on all attacks made that round. Successive insight checks grant advantage on attacks during the round that the insight check was made.

Impeccable Insight

Starting at 9th level, when you make a knowledge check to learn about a creature you have studied, you can treat any die roll below 10 as if it were a 10.

First Strike

Starting at level 13, you may add your intelligence modifier to your initiative rolls.

Precognition

By 17th level your senses are so attuned you can practically divine into the future. You can predict a key failure in your enemies defenses- an opening for a kill shot. When a target is under the effects of your Educated Sneak Attack, you can make a Prediction. You must make the prediction before the attack is rolled. If the attack hits, it is a critical hit.

You may use this feature a number of times equal to your intelligence modifier per long rest.
