You summon a fiery blade in your free hand. The blade resembles a scimitar in size and shape and lasts for the duration. When you release the blade, it disappears, but you can recall the blade as a bonus action.
You can use your action to attack a melee spell with the Fiery Blade. If hit, the target suffers 3d6 Fire damage.
Suppose you had the opportunity to cling to the weapon, could a Moon Druid use a Flame Blade after being cast at Wild Shaped?
