Question about Crit marcos

Is it possible to make a macro with a crit range of 19 but in 20 it adds something different. My class allows me to crit from 19 to 20. But my weapon on a 20 adds a special extra damage die. Is it possible to just have a macro that does all that ? If it isn't that's fine happy to just do it myself.

You could add that to your character. /roll 1d20cs&gt;19 But if you're using the D&amp;D 5e by Roll20, then you can just adjust the weapon attack on the PC character sheet directly: <a href="https://app.roll20.net/forum/post/5812466/certain-weapons-crit-on-a-19" rel="nofollow">https://app.roll20.net/forum/post/5812466/certain-weapons-crit-on-a-19</a> &nbsp;

I don't think it's possible to set two different crit points on a single roll. Your best bet would be to include a macro that they player can manually trigger in the event of a natural 20, while still preserving crit functionality for 19-20.

You can kinda do it: &amp;{template:default} [[floor([[1d20cs&gt;19]]/20)*2d6cs0cf0]] {{Attack Roll=$[[0]]}} {{Bonus Damage=$[[1]]}}
