Elemental Strike

As part of the action used to cast this spell, you must make a spell or weapon attack (your choice) with a weapon you are holding against one creature within the spell's range, otherwise the spell fails. On a hit, deal damage as normal, except the damage type is replaced with one of the following types(your choice): Acid, Cold, Fire, Lightning, or Thunder.

When you make this attack, the weapon does not require ammunition as it is magically conjured in the form of the chosen type of damage.

At Higher Levels. The damage the creature takes on a hit increases by 1d8 of the chosen type at 5th level (1d8), 11th level (2d8), and 17th level (3d8)
