Since you’ve already done a roll for each, Jarynth May as well do each roll for himself as well. Doing them seperately like that now would be pointless at best since that just means Jarynth won’t be able to do any better then what Shem’et did, though ultimately that’ll be Black key’s choice. Presumably you’re both traveling together so unless Jarynth intends to move ahead of Shem’et, doing less will simply allow him to cover more ground.
