This particular system question crops up quite often. Without using a script, you can do the roll something like /roll ?{Number of Dice|1}d10>6sa This will give you an output that tells you the number of successes vs difficulty 6, and show the dice in ascending order. You can then see how many are 10s, and manually add +1 for each double. You can also check out the Power Cards thread, and ask there if anyone has a way to handle the special rule that applies on 10s. It hink it should be do-able, but I dont use Power Cards.
