After the third pair of wizards have come out (Happens around 70% transmatting), for the love of all that is holy, step out of the zone.
Sincerely,
Everyone who knows how to turn the public event heroic
Edit: Killing the shriekers is what triggers the heroic event. If the transmat progresses enough, the shrieker basically opens and closes almost straightaway.

I have only done this event twice and had no idea. That's a stupid mechanic but thanks for the heads up.
