I am trying to implement mastery dice into this macro: /em Rolling for something... vs. TN ?{Target Number|14} /r ?{Number of Feat Dice|1}t[feat] + ?{Number of Success Dice|0}t[?{Normal or Weary|normal,normal|weary,weary}] + ?{Modifier|0} Thats the flexroll macro from the common TOR Roll20 guides. If you don't know, Mastery dice are a mechanic introduced in the Adventurers Guide where you add 1 or more Mastery dice to your dicepool, then remove that number of lowest rolls. In other words, if you have a Song skill of 3 and 2 Mastery Dice in Song, you roll 5 success dice and remove the 2 lowest dice results. I know nothing about macros, but a friend of mine suggested this: +?{Mastery dice|0})d6d?{Discard|0})]] Obviously this macro isn't perfect, nor does it interact with the custom roll tables for TOR or any of the other macros or scripts so I can't actually use it for my TOR game. I need some help from people who are better at macros than me and my friend, so I'm turning to the Roll20 community here on the forum. Any help would be very much appreciated.
