I think it strongly depends on whether the monsters in question spawn as yours, or as "special monsters". For instance, the Wraith Crown seems to create "special monster" skeletons, that, when slain, merely produce a "Special monsters are routing" message, and have no effect on you. Did the LotDS produce this message when his lions bought it? If so, the Lord of the Desert Sun is a much more attractive pretender chassis, since he lacks the consummate cowardice of other "accompanied by X" chassis.
