rank of the resulting pet = [(rank of the main pet + rank of the assistant pet)/2] +/- 20 (on higher ranks the +/- 20 changes to +/- 10 or even less, making it more difficult to get high ranked pets)
Here's a list with the ranks: http://forum.ao.igg.com/viewthread.php?tid=57444&page=1#pid999737
High ranked items in the random slot can improve your chances of acquiring a resulting pet with a higher rank.
And btw, Naga Siren? Is that a caught universal pet? Because I've never heard about it o.o (am not a big pet fan xD).
