In the Waterdeep: Dungeons of the Mad Mage Roll20 Adventure Trailer, it shows a DM dragging a card from the Rune Deck, and when it hits the board there's a graphic where the blue Boon rune appears on the page (see 0:47 here: <a href="https://youtu.be/Nmp_TjzyltA?t=47" rel="nofollow">https://youtu.be/Nmp_TjzyltA?t=47</a> ) - how does one create this? Was it just a video effect added for the trailer that doesn't exist in the product?
