At mephit fight in bog, every mephit summoned another. None of them fought or moved and took max time before changing initiative. Needless to say, I have been in this fight for a LONG time because 3 of my characters went on the rock of action losing (I made a thread on it) so I have 1 person fighting them getting a cantrip a round. But yeah, there were like 10 just hanging out doing nothing the entire fight.
