You can summon the fey creature of Challenge rating 6 or lower, or even a Fey Spirit which shall take the form of the beast of challenge rating 6 or lower. It also appears in an unoccupied space which you could see within a specific range. Of course the fey creature shall disappear whenever it drops to 0 Hit points or else whenever the spell ends.
The fey creature is a friendly for you and also your companions for a particular duration. Roll an initiative for the creature, which usually has its own turns. It shall obey any type of verbal commands which you do issue to it (no action required by you), as long as they were not violate its Alignment.
Suppose if you do not issue any type of commands to a fey creature, it will depend itself from the Hostile creatures but otherwise it takes no actions.
Anyhow, if your Concentration has been broken, then the fey creature does not be disappeared. Instead, you can lose the control of a fey creature, it shall become the hostile toward you and also your companions, and it might attack.
Usually, an uncontrolled fey creature can not be dismissed by you, and it shall disappear one hour after you’d summon it. The DM has the fey creature’s Statistics.
