Pyroclastic Command

You may shape and sustain your fire effects with precision. When you cast a Fire spell that creates a persistent area effect (Wall of Fire, Fire Storm, Smoke Cloud, Engulf in Flames area), you may reshape the area as a Bonus Action on subsequent turns - moving it up to 5 meters, changing its shape within the same total area, or splitting it into two separate zones of half size each. Additionally, persistent fire effects you control no longer require concentration - you may maintain up to two simultaneously.
