Help on making an FOF disappear when...

EDIT: Nevermind got it working :D

Try replacing the crawla with the special switch type used in Azure Temple Zone. That zone also has a nuke gimmick if I recall correctly. Then follow the wiki tutorials on how to use that switch type as a trigger to shatter a FOF.

EDIT: Seems like the wiki isn't up to date regarding this. Maybe ask a developer on how to set this up?

EDIT2: Maybe you can do it your way by following these:

It's OK, Tyrannic, I already figured it out. It works beautifully.
