Macro for Double Damage on Crit (No Specific Template)

Hiho, I'm looking for a way to create a macro which rolls an attack, checks if a crit appeared and doubles the dmg if so. But not double damage like rolling 2 same sided dice instead of one but doubles a damage roll what has already been made.  I.e. Rolling attack 1d20 and 2d6 damage. attack: 20 -> crit, damage 10. So the macro should make a 20 out of the 10 somehow. I'm tried it with a check on crit to put out a 0 or 1 and do like 0 or 1 * damage roll (reuse) and adding those up at the end. But it does not work the way I tried it. &{template:default} {{name=Attack Macro}} [[ [[1d8+?{Damage|0}]] + [[ [[floor([[1d20cs>20+?{Attack|0}]]/[[20 + ?{Attack|0}]])]]d8+?{Damage|0}[CRIT] ]]]] {{Attack =$[[1]]}} {{Damage=$[[0]]+$[[4]] = $[[5]]}} Found this macro from GiGs  and tried to work from there. Below is what I tried. &{template:default} {{name=Attack Macro}} [[ [[2d6]] + [[ [[floor([[1d20cs>20]]/[[20]])]]*$[[0]] ]]]] {{Attack =$[[1]]}} {{Damage=$[[0]]+$[[4]] = $[[5]]}} Hope that someone can help me with this :) PS: Is it possible to do a text output on Crit?

To your last question, no it's not possible to do text output on a crit. :( Regarding your roll I see this: /[[20]])]]*$[[0]] First, I don't know why the 20 is an inline roll. You could just do /20)]]*$[[0]] But the bigger issue is this part: *$[[0]] You cant treat the reused roll as a number. It's an object of some sort, and can't be used in arithmetic here. Rather than looking for a 0 or 1, I'd be looking at getting a 1 or 2, and multiplying the original 2d6 roll by that. Try this: &{template:default} {{name=Attack Macro}}[[ [[2d6]] * [[ 1 + [[floor([[1d20cs>20]]/20)]] ]] ]] {{Attack =$[[1]]}} {{Damage=$[[0]] * $[[3]] = $[[4]]}}

Thanks! That worked just fine!
