Is Elemental Weapon Good?

Overall Rating: Orange. This means that elemental weapon is an OK spell.

Overall Notes: The damage just isn't great for a 3rd-level spell and concentration. If damage vulnerabilities were more common in 5e, it could be worth it. Unfortunately, as it stands it's just not an effective use of the resources is requires.
