Weakness to Elements

The caster weaves their magic into a shape resembling that of a needle, thorn, shiv, etc, then selects one damage type for the spell to represent, excluding piercing, slashing, and bludgeoning. The spell then seeks out a single target of the player's selection within 30 feet and inserts itself into the target thus imposing a Constitution save equal to your spell DC. For the next 3 rounds, on a failed save, the target will have disadvantage on saves against the damage type associated with the spell and have their resistance to the spell's damage type lower by 1 level; however, no more than 1 needle may be used on a single target.
