crit damage roll

yeah im having trouble setting up a macro that when it rolls 16 or higher that it rolls critical damage and when it rolls lower than 16 it rolls regular damage for example say on a /r 1d20 i get a 16, i would like it to automatically do a (2d8)*3, but on a 15, do a 2d8

Not possible without using the API, a mentor level feature available to GM's.

The closest thing you can do without having API is something like this, using inline rolls. /em makes an attack Attack: [[1d20+?{Attack Bonus|0}]] vs AC, 18-20 = crit Hit: [[1d8+?{Damage Modifier|2}]] damage Crit: + [[1d8+?{Damage Modifier|2}]] extra damage It shows you what the crit range is, gives you the base damage, and the extra damage on a crit. In this example a weapon that crits on a 18-20/x2.

how would you do a x3 crit weapon?

nvm i figured it out
