Multiple Reroll once

Hello everyone! I am playing an Italian RPG called "L'Ultima Bomba" which has a system of Merits/Flaws  that allows a  reroll (only once) of any natural 1 or 2 (Merit) or any two higher values of the dice (Flaw). Merits and Flaws may apply on the same roll, i.e.: 1d10 M/F, the Player has to reroll once if the result is 1, 2, 9 or 10. I tried several combination of RO but nothing is working.  For example: ro<2ro>10 not working ro<2>10 not working Is that possible or not?

Well that's an odd one, the other dice references work by lumping them in a happy old string. But you're right, multiple 'reroll once' commands don't seem to work. Until someone clever comes up with an answer here's a workaround: /r 10d10ro<2sdcs>9 That will roll 10d10, rerolling once on a 2 or lower, then group 9's and 10's at the top, highlighted green, so they're a bit easier to reroll manually.

Thanks, we'll try this workaround too!  PS: I didn't specified that this system uses only D10 for common abilities rolls, plus D4 to D20 for damage/magic/etc... If  you roll two or more dice, you keep the better result (and reroll once if you have Merit/Flaw). So, for example: 2d10 to roll with Merit AND Flaw, result is 2 and 9, I have to reroll both and keep the final result.  Anyway the workaround should work also with one dice, I'll try for sure!
