there was a thread two years ago here: <a href="https://app.roll20.net/forum/post/2368687/slug%7D" rel="nofollow">https://app.roll20.net/forum/post/2368687/slug%7D</a> the link to the edited API script (CthulhuTech dice) for OVA has expired or been removed. I am unsure how to edit the Script so that its compatible to OVA (since ova doesn't have "straights" but has Doubles or highest number as the roll it takes). An API is need to make a macro that can do the math for dice rolls in OVA, and would speed things up for players who do math slowly.
