The Visitor Event Guide/Discussion.

so anyone have a tip as to how to do the boss? He does this "You've been immobilizes and will explode unless someone helps you!" move, except no where does it tell you what to do to "help". Actually that's definitely the biggest problem with this, there's practically no direction at all, you just have to guess wtp's going on and hope it works out. So yeah if anyone has advice on how to not explode on the final boss that'd be nice.

I think you do have to hit your party member with a normal atk to cancel the effect. Seems to be working but the lvl 60 pq took me about 3 hits I think to free someone.
