Double Brew Feature 9
You know your formulas so well that you can concoct two items at once.
When using the Quick Alchemy action, instead of spending one batch of Infused Reagents to create a single item, you can spend up to two batches of infused reagents to make up to two alchemical items as described in that action. These items do not have to be the same.
