Elemental Coating

You brandish the weapon used in the spell’s casting inset with a gemstone befitting the chosen damage type of the spell (as found in the below table) and coat it in the element. The next time you hit a creature with a weapon attack before this spell ends the attack deals an extra 2d6 damage of the chosen type to the target, they must then make a Constitution saving throw or suffer an additional condition (as found in the below table) for the next minute on a failure. Once per round at the end of their turn they may repeat this Constitution saving throw to try and end the additional condition.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the extra damage increases by 1d6 for each slot level above 2nd.
