I am playing this with my wife and we are loving it, with only a few minor complaints so far.
The familiar teleport pyramids used to quick travel from deep dungeons are a welcome sight (I remember them from the first Divinity game). However, when I use it, only me and the two henchmen who are chained to me will be teleported. As a co-op player, she is not chained and therefore gets left behind.
Am I overlooking something? Is there a way to allow her come with me when I use the pyramid?
If you're leaving one pyramid behind as a beacon to return to, you can always transfer the one you're actively using to each other by dragging and dropping it on your respective portraits - even if there's a vast distance between you.
I believe there is a range limit on abandoned pyramids before they'll return to your inventory (at least there used to be). While there are all sorts of clever things to do with these devices, I believe the main purposes of them was to allow the two main characters to easily teleport *to* each other (rather than away from each other) - meaning both of you keep one in your inventory.
