Signature Tactic

Annihilation

You learn how to leave no one left alive on a battle field, because survivors can only mean trouble for the future. When you drop a creature to 0 hit points, you can spend a dangerous intelligence as a reaction in order to allow a creature within 30ft of you that can see and hear you to make a weapon attack against a creature with range, if the attack hits the creatures speed is reduced to 0 until the end of its next turn. 

Blitz

You charge the enemy when they least expect it to exploit when they are vulnerable. You can spend one Dangerous Intelligence as an action to let yourself or an allied creature within 30ft that can see or hear you move half their movement towards a creature and use an attack action against the it. The creature must make a dexterity saving throw or be knocked prone, and If the allied creature moved at least 10 feet in a line towards a target an all attacks made hit then the creature then it has disadvantage on the dexterity save.

Fake out

You can trick you enemies by having them believe you are going to attack one way and attack another. You can expend one dangerous Intelligence as a bonus action in order to let one allied creature within 30ft of you to move up to half their movement speed, if the allied creature stops moving within melee attack range of a creature that is in your range, then you can make a weapon attack with advantage against that creature.

Infiltration

You learn how to exploit a creatures trust in order to gain an opening. When you or a friendly creature within 30ft of you that can see or hear you makes an attack against a creature that see's the attacker as no threat to there life, you can use a Dangerous Intelligence to make the attack a critical hit and the creature must also make a constitution saving throw or be stunned until the end of its next turn.

Magic Exploit

You learn how to take advantage of openings that magic can provide. When a creature within range makes a saving throw against a spell that does not target you, you can expend a Dangerous intelligence in order to use your reaction to attack the creature, the creature must succeed on a dexterity saving throw or have disadvantage on there next saving throw from a spell until the end of their next turn.   

Adaptable

When you roll initiative and have no dangerous intelligence's remaining, you regain one dangerous intelligence.
