Positron posted on this earlier. Good info, too.
Halloween Info
Eochai will respawn somewhere in the zone whenever he is defeated.
10% of the time, that respawn is Jack-in-Irons instead.
Also, Jack only appears in level 20 and higher zones.
So... if you are hunting Jack and come across an Eochai, defeat it just so the respawn can happen and there is a new chance at a Jack showing up. Leaving an Eochai around while you look for a Jack is actually detremental in finding Jack.
