I posted this over on the Roll20 support forums but I figured I'd ask here as well.

Basically I want to incorporate bonus damage dice in my attack macros. Right now I've got this line:

/roll 2d20k1+10 /roll 1d12+8

For one of my Avenger's attacks. basically I want to incorporate that 1d6, but only have it rolled and added to the attack damage total if the higher of the two d20s is a 20. I'm not sure how to do that (or if such a feature has really been implemented) and the built in exploding dice feature /roll 4d6! for example adds another die to the first roll of the same type on a crit, but doesn't seem to over any other application.

Let me know if this is too specific or not in the comments. Thanks.

Also, Roll20 or Roll20.net for the new Roll20 tag? –  Joshua Aslan Smith Jun 21 '12 at 6:06
I don't think periods are supported in tags –  wax eagle Jun 21 '12 at 11:41
I've read their documentation and it doesn't look like this is a supported use case. Perhaps emailing support and asking (then self answering when the syntax becomes available?) –  wax eagle Jun 21 '12 at 11:45
Yes I asked them as well. I don't think its supported since there wasn't any documentation on it, but I thought I'd ask if someone had figured it out and it just wasn't documented yet. I will self answer if/when I receive an answer. –  Joshua Aslan Smith Jun 21 '12 at 16:08

I think the best you're going to come up with at this time is to add a macro for your roll so

 /roll 2d20k1+10

And then a macro for each of your damage expressions, both the critical damage and also the normal damage so

 /roll 1d12+8


 /roll 20+1d6

You'll have to figure out when to roll which on your own.

The other option would be the set up your attack and regular damage as a macro and then have your critical damage as a second macro that you use to replace your normal damage roll in the even of a critical hit.

I still strongly recommend asking roll20 for native support, but this is a quick fix for now.

Wax, thanks again for your prompt response and input. I figured I could just add the d6 to the same macro with the explanation being crit damage die and just add it if I crit. I thought it and interesting question though and it was a good excuse to throw in the roll20 tag for future questions. –  Joshua Aslan Smith Jun 21 '12 at 16:10
@JoshuaAslanSmith definitely –  wax eagle Jun 21 '12 at 16:12
