Jsk Commander

Formation
At 3rd level, you can create a formation of warriors to dominate the battlefield and assist in your endeavours. As a bonus action, you and up to five willing creatures of your choice within 10 feet of you become a formation. A creature leaves the formation if it spends 1 minute outside the range of your formation, or ends its turn outside the range of your formation. If a member of your formation uses the Help action when you perform a Charisma ability check, the roll gains an additional +1 bonus for each unique member of your formation that uses the Help action, to a maximum bonus that can be no greater than your proficiency bonus.

The range of your formation increases by a number of feet equal to 5 x your Charisma modifier (a minimum of 0), and the amount of allies that can join your formation increases to 10 at 10th level. A member of your formation can ignore the range limit on the Help action when using this feature.

Unified Offensive
At 3rd level, when you make an Attack, you can call upon any number of allies that are part of your formation to also make an Attack against the same target. You can choose which Attack roll to use, and all other Attack rolls are discarded. Attacks made by members of your formation cannot be made with advantage when you use this feature (excluding you), even if an effect would normally allow them to do so. You can use this feature a number of times equal to your Charsima modifier (a minimum of 1), and you regain any expended uses when you finish a short or long rest.

Great Leader
At 7th level, you become an inspiring example to your formation. When you score a critical hit with an Attack, all members of your formation gain the Motivated effect (excluding you). When a creature with the Motivated effect makes an Attack, it gains a bonus to the attack and damage roll equal to your Charsima modifier (a minimum of 1). The Motivated effect is lost when an Attack is made, or after 1 minute.

Unified Strategy
At 10th level, when a member of your formation makes an Attack, any other member of your formation can use its Reaction to use the Help action, granting the attacker advantage on the roll. A member of your formation can ignore the range limit on the Help action when using this feature.

Supreme Leader
At 15th level, the Motivated effect you give to your formation is not lost when an Attack is made. When a creature uses your Motivated effect, it lasts until the end of that turn. Additionally, if a creature with your Motivated effect has advantage on it's Attack roll, then the attack and damage bonus of the Motivated effect is doubled.

Unified Strength
At 18th level, when any member of your formation makes an ability check or a saving throw, any other member of the formation can use its Reaction to take the Help action, granting advantage on the roll. A member of your formation can ignore the range limit on the Help action when using this feature.
