Cross, it's a better idea for Rybka to be the primary actor on this test, 'cause that way I can add your successes to my dicepool. Chances are that the final dicepool will be bigger that way (I'm going to add my 20-something to your success and use this as my dicepool; if we did it the other way, you would add your 12 to my successes which would be far fewer). The auxiliary actors always roll the dice first.
