Do It For Me! As a bonus action Blue Lili can use a legendary action on a creature is charmed to her she can command it to do one action that it is able to do. It also could be a quest, task.

On failed save it does it. If the creature is willing to do, there is no need to a save check. This command cannot lead to self harm, or suicidal actions (only if the creature doesn't know the dangers of do as the command says).
