Tactician

Tacticians, being useful as a tactician but still capable of handling their own on the front lines, extend from a variety of places and backgrounds, all having spent a large portion of their life studying the nature of battle and much more of their time in practice. As a coordinating factor, Tacticians often lend an upper hand to their teammates as well as making the fight sway in the favor of those who fight on his side. With careful planning and will of his allies, Battle Strategists ensure the fight is won before it starts.

Coordinated Assault

Beginning when you choose this archetype at 3rd level, you gain proficiency in investigation.

Additionally at the start of your first turn in combat, choose a number of allies equal to your Intelligence modifier within 60 feet of you. These creatures all benefit from an additional half of their movement speed, rounded up until the start of your next turn. Any attacks made on these creatures while using this movement are made at disadvantage. 

Combat Analysis

Starting at 7th level, as an action, you can analyze a creature and their fight patterns to determine the best way to approach. Make an Insight check. 

• On a 5 or less, you gain no benefit from this ability.
• On a 6-10, you learn one useful thing about this creature.
• On 11-15, You learn two useful things about this creature.
• On a 16-20, You learn three useful things about this creature.
• On 21-25, You learn four useful things about the creature.

• On a 26 or higher, you reap every useful piece of information from a creature that you stand to benefit.

Information gained from this ability is as follows- 

• The creature’s designation (fey, fiend, elemental, etc.)
• Any resistances, vulnerabilities, or immunities the creature has.
• Whether or not the creature has any legendary actions or legendary resistances.
• The creature’s effective range.
• One of the creature’s saving throw modifiers (Player’s choice)

The player can choose what information he gleans from this ability but is limited to the roll total.

This ability can be used a number of times equal to your proficiency bonus and returns on a short or long rest.

Battle Awareness

Starting at 10th level, you can add half of your intelligence modifier, rounded up, to your AC while standing within 5 feet of an ally. The ally also benefits from this buff. This effect can only be used on one ally at a time and a creature can only be affected by this ability once.

Calculated Advantage

Your constant attention to detail allows you to provide others with the resources necessary to perform their best in battle. You can spend 10 minutes coordinating with your team, providing the insight necessary to perform better on the battlefield. After this 10-minute period has passed, a number of creatures equal to your intelligence modifier benefit from the following-

• They have advantage on their next initiative roll.
• Once, after rolling an ability check or saving throw but before knowing the outcome, they can make that roll as if they had proficiency in it. If the creature already has proficiency, it can be rolled as if it had expertise. If the creature already has expertise, they can roll with advantage. If this creature already has all of these benefits, this ability does nothing

This ability can only be used once per long rest.

Optimized Resources

Starting at 18th level, on your turn as part of the attack action, you can forgo up to 2 of your attacks and instead use that time to issue a command to another willing creature, giving them an extra attack on their turn instead. A creature cannot benefit from more than one additional attack on their turn.
