i don't think so, it just allows them it at first level instead of fourth, i could be wrong tho.
i have the same combination in my party, i'm curious if they would stack, seems like a lot of dice rolling tho...
Well I would rule that you roll twice and then decide if you want to keep one of those results or whether you want to roll twice again and have a second choice of two.
It'll be a gamble rolling the second time because you could get a worse selection.
