Help with Macro (Looking to replace vlaue below 3 with 3's ie Deadly sneak)

Looking to see if there is a way to replace a value on a die with another value. So in deadly sneak it says that you replace every 1 or 2 rolled on a sneak attack with a 3, is there a way to make the macro do that for me? Thank you in advance. :3

{1d6, 3}kh1 should replace each 1d6 roll.

Except Roll groupings can only compare  rolls or  numbers not a roll and a number. You can work around this by using a fake die roll.   Formula for 2d6 replacing rolled 1s and 2s with a 3: [[ {1d6,1d1+2}kh1 + {1d6,1d1+2}kh1 ]] Wiki Roll20: Grouped Rolls

Scott C. said: {1d6, 3}kh1 should replace each 1d6 roll. That is the cleanest way ( keep highest roll ) but you can also just setup a  reroll on anything 2 or less: 1d6r<2

Just getting errors with that, please can you further explain the process, likes lets say this is the part of the code {{Damage= [[3d6+7]]}} and lets say all 1's and 2's are 3 due to a feat , how would you write that and explain how it works >.< thanks :3 

ok got it sorry was like reading it and just saw the new posts. Thanks alot guys :3 Super useful info, and the whole Keep Hihest Roll thing will come in handy :3 THANKS AGAIN! 

Yeah, sorry, forgot to put the roll expression in the second argument

Try This: {{Damage=[[ {3d6,1d1+8}kh1 + 7]] }} 3d6 == [Normal damage roll] 1d1+8 == [Roll Comparison that equals your Minimum Possible damage roll, due to your Feat] The Curly Braces Denote that this roll is a Grouping. The 2 rolls are seperated by a comma. kh1 == Keeps the Highest Value between the 2 rolls. Then your modifier of 7 is added. For Example:  You roll your damage dice and come up with a 4,2,1. Total of 7. That roll is then compared to the other roll in the grouping which is 1+8 total of 9. Then Macro then takes the Highest of the rolls and then adds your modifier of 7 for a total of 16 damage.

Then Macro then takes the Highest of the rolls and then adds your modifier of 7 for a total of 16 damage. You can't do the 3d6 all together because the feat replaces all 1's or 2's with a 3, so if you roll 3d6 and get 1, 6, and 6 the macro won't fire because 6+6+1 is still higher than 9, but with the feat this should have been converted into 6+6+3.

Doh, see how good I am at maths!

Hey, I'm great at macros. Just look at my totally error free suggestion above. ;)

How about: [[ [[{1d6, 3d1}kh1]] + [[{1d6, 3d1}kh1]] + [[{1d6, 3d1}kh1]] ]]
