Spell Description

You evoke a fiery blade in your free hand. The blade is similar in size and shape to a scimitar, and it lasts for the duration. If you let go of the blade, it disappears, but you can evoke the blade again as a bonus action.

You can use your action to make a melee spell attack with the fiery blade. On a hit, the target takes 3d6 fire damage.

The flaming blade sheds bright light in a 10-foot radius and dim light for an additional 10 feet.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for every two slot levels above 2nd.

Is Flame Blade Good?

Overall Rating: Orange. This means that flame blade is an OK spell.

Overall Notes: This does slightly more damage than flaming sphere on hit, but has a lot of caveats. First, you have to be within melee range to you can be attacked and lose concentration. Second, it takes your action to attack using flame blade whereas you are able to cast spells on subsequent turns after casting flaming sphere. Yes, flame blade has a longer duration, but that rarely comes up in 5e combat. If I were playing a druid, I would take flaming sphere over flame blade most times.
