Reroll as long as you get X

[michalzkosmosu]

In my own system if you got 6 on a D6, you reroll and you do this as long as you get 6 (theoretically, you could have a score of 58 or more from one dice). So it would be awesome if you add option like /r 3d6r6 but to address this situation.

Thank you for an awesome bot. And your work.

Already exists, it's the exploding dice. Add an exclamation point to the end of the dice you're rolling.

(/r 1d6!)
