Because it's not automatic. The player has to look at the dice rolls and decide which dice to reroll, if any, up to Charisma Mod, and get stuck with the new roll. Setting a floor doesn't work because a 2 could be come a 1. If the roll is really bad (e.g., all 1s), you can't reroll all of them. The player may decide that they don't want to spend the sorcery point, or may decide that, despite being below average on the total, it's close enough and not worth the risk of getting worse. Will M. said: Why not build one of the following dice formulas and let Roll20 Dice Mechanics do the work for you? Replace all 1s with 2s: {[[d6]],[[d6]], [[d6]], [[d6]], [[d6]], [[d6]], [[d6]], [[d6]], 2,2,2,2,2,2,2,2}kh8 Replace all 1s and 2s with 3s: {[[d6]],[[d6]], [[d6]], [[d6]], [[d6]], [[d6]], [[d6]], [[d6]], 3,3,3,3,3,3,3,3}kh8 Reroll 1s and 2s: 8d6r<2 Reroll 1s and 2s (only once): 8d6ro<2 Example Visual Dice syntax is: [d6]5[/d6] should display the number 5 on a 6 dice font. This also didn't work.
