What do chain bots do in Holo Battle Interlink?

The timer is the thing to play around: a new chain robot arrives every 45 seconds for as long as the fight lasts. It is a modifier rather than a fixture of the mode, so it shows up on some runs and not others. The first Holo Interlink floor has one, and so does the Hula Flower route.

A restrained player is out of the fight for a moment, and in this mode that costs more than usual. Each player has only one main Aniimo on the field, and the others come in only as assists, so whoever is chained has nothing else fighting for them until it wears off. Deal with each robot when it appears rather than letting them stack up on top of the boss.

The restraint is temporary, but a chained player standing in boss damage is still at risk. You can revive only once per run, so getting caught at the wrong moment can use up that one revive.
