FF XIV Red Mage Macro
This macro allows you to instantly choose between Verfire and Verthunder. If you are verfire ready, it will cast Verfire, and the macro will not cast Verthunder, since you are already casting. If you are NOT verfire ready, the Verfire cast will fail, and the macro will cast Verthunder. Since the icon in use is the Verfire icon, you will know when you are verfire ready, as it will light up.
