The way I see it, here are the options you have: Use one of macros above, relying on roll highlighting (red on a natural 1) to indicate that you must mentally subtract 7 from the macro output. Ask your GM to create a Rollable Table to the specifications provided by Franky H. Write or request an API Script to handle rolls. (Access to the API is available only in games in which the game's Creator
currently has an active Pro subscription.) Use math to emulate a die roll, e.g. /r 1 + {[[d19cf0]], 7}kh[[d20>2cs0]] or /r 1 + {d19cf0, 7+0d0}kh[[d20>2cs0]]
