Elminster's Elemental Epee

You conjure a long blade made of an elemental damage type of your choice (Acid, Cold, Fire, Lightning, Poison, or Thunder) in your free hand. The blade is similar in size and shape to an Epee, and it lasts for the duration.

When you cast this spell, and as a Magic Action on your later turns, make up to two Melee Spell Attacks against one or more targets within range. On a hit, you deal 3d6 plus your spell modifier of the chosen damage type.

Regardless of your chosen elemental damage type, the blade sheds Bright Light in a 10-foot radius and Dim Light for an additional 10 feet. If you let go of the blade, it disappears, but you can evoke the blade again as part of the Magic Action you use to attack with this spell.

Using a Higher-Level Spell Slot. You deal 1d6 additional elemental damage for every two slot levels above 3rd, and may make an additional spell attack as part of your Magic Action for every three spell slot levels above 3rd.
