I prefer best two-out-of-three, because i don't want it to be based entirely on luck. (tho it still will be, it won't be based off the luck of one 20 or one 1.)<br/><br/>I disagree with more rolls, though as Netjak suggested. There's feats that provide more rolls.<br/><br/>The problem with vore not being viable is until later, it's got a 50/50% chance of being successful and also action economy. As long as the prey isn't murdering everyone in the time that it takes you to eat it, then it's viable.
