You Set Them Up, I Finish
Add your Charisma modifier to the damage dealt by your ally (double your Charisma modifier at 5th level; triple it at 8th level). In addition, during your next turn, you gain a +2 attack bonus with melee attacks against the enemy that your ally hit.
The target ally also gains the damage bonus with any other attacks it makes against the same enemy this turn.
The command now costs 3 command points to use.
Your attacks that benefit from the +2 attack bonus against that enemy also add triple your Charisma modifier to your damage on a hit.
