Each target makes a WIS saving throw (DC 17) and is charmed if it fails for 1 hour, or until it takes any damage, Agent Peacock attacks it, or it sees Agent Peacock attack or damage its allies.

Fey Ancestry. Agent Peacock has advantage to save against being charmed and magic cannot put Agent Peacock to sleep.

Bardic Inspiration (5/Short Rest). As a bonus action, a creature (other than Agent Peacock) within 60 ft. that can hear them gains an inspiration die (1d10). For 10 minutes, the creature can add it to one ability check, attack roll, or saving throw. This can be added after seeing the roll, but before knowing the outcome. If a creature has a Bardic Inspiration die from Agent Peacock and casts a spell that restores hit points or deals damage, the creature can roll that die and choose a target affected by the spell. Add the number rolled as a bonus to the hit points regained or the damage dealt. The Bardic Inspiration die is then lost.

For 1 minute or until Agent Peacock's concentration ends, Agent Peacock can cast command as a bonus action on each of their turns, without expending a spell slot. Creatures charmed by Agent Peacock automatically fail saving throws against the command you cast with this feature.

Fey Step. Once per short rest as a bonus action, Agent Peacock can magically teleport up to 30 ft. to an unoccupied space they can see. Immediately after they use their Fey Step, up to two creatures of their choice that Agent Peacock can see within 10 feet of them must succeed on a Wisdom saving throw (DC 17) or be charmed by Agent Peacock for 1 minute, or until Agent Peacock or their companions deal any damage to it.
