How do i check dices for failure which i do not keep?

In "Splittermond", a german rule system you can perform risk checks. For that you throw 4d10. If you throw 2 times a 1 or a 1 and 2 you perform a critical failure. But if you don't perform a critical failure you can keep the best 2 dices. For exapmle: 7, 8, 2, 2 is a 15 (7+8 or 4d10k2), but 7,8,2,1 is a critical failure (Because there are a 2 and a 1). How can i perform this with macros?

This would most likely require a custom API script to handle, which a pro level perk.

As Kyle G. said, the total automation of failure detection or failure announcement is not possible without the assistance of an API Script . (API access requires a Game's Creator to have an active Pro subscription.) You could possibly make determining whether or not you rolled a failure by using Roll Highlighting and Sorting Dice . For example, [[ 4d10kh2cs2sa ]] This macro highlights 1's in red (by default), but also highlight 2's in green (instead of 10's, by default). This is so that if both a 1 (red) and a 2 (green) are rolled, the inline roll will be highlighted blue, indicating critical failure. If the inline roll is highlighted green or not highlighted, then that indicates that you have not rolled a critical failure. If it is red, you'll have to actually check the inline roll to see whether or not you rolled only one 1, or whether you rolled a critical failure. The dice sorting may help with this.
