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