Does the Green-Flame Blade cantrip work with the Zephyr Strike spell?
Specifically, I am unsure as to whether the Zephyr Strike spell (XGtE, p. 171) requires you take the Attack action. Its description states:
Once before the spell ends, you can give yourself advantage on one weapon attack roll on your turn.
I'm unsure whether the making of this attack would fall under the Attack action, or if it could work in conjunction with Green-Flame Blade.
