I tried using gems once. You pay up front then roll. So if you roll a 20, it will up it to 21.

I think it sucks because the chance of rolling 20 is pretty low anyways, and you do have to pay up front. You can only pay once (unless they changed it recently). Might be willing to pay 5-6 gems to make sure i roll 20+!
