You remember correctly. The difference between the priests and the wizards is VERY obvious. Nothing else is showing any clear sign of making a difference, even whether or not the priest is a prophet.

Interestingly, it has to be an Illithid priest. A Telestic Animate, for example, can't use the gate.

Thank you! Thanks to your advice I've been able to play with wonderful Vastnesses, Things That Should Not Be, Greather Othernesses, and a host of other unspeakable beings from beyond our understanding.

And casting Gift of Reason on them was fun, too.
