Coughing Dragon

Choose either auditory or visual effects. The display gains that trait, and you attempt to counteract one or more effects in a 60-foot area that have this trait. On a success, the effect is suppressed until the start of your next turn, rather than ending entirely. Use your fireworks-lore modifier as your counteract modifier, and your counteract rank is equal to half your level (rounded up). You can spend 2 versatile vials and 3 actions (instead of the usual Cost and actions) to create an even bigger coughing dragon display that attempts to counteract both auditory and visual effects at the same time.
