Wait Encounter in EZScript.

[John Jr.]

Hi guys, I need a little help.
I need to script a encounter with the heroes fighting an invincible opponent for 120 seconds before he's teleported away. I know there is a "Wait" encounter in EZScript, but I don't know the right order to use it.
It should be like this?

encounter 1: Hunt: badguy hunts the heroes, heroes must survive for 2 minutes.
encounter 2: Wait: Minimum time: 120, Maximum time: 125
encounter 3: Cutscene: Badguy disappears, heroes win.

Thanks in advance!
