I found copies I made from a 3e-era book describing Oitiluke's answer to something I've been looking for for a while: I want a monster that can summon its buddies and all concentrate on one target.
I still am flummoxed about the fact that my 3e Bard could not cast Tenser's Disk to move stuff from a shipwreck up to the salvage ship.
