Swirling Sphere

A ball of swirling energy is conjured and held by the user. The sphere can never leave the user's hand or casting device (such as a staff) or it will dissipate. It is then used to drill a hole through enemies or the environment. This spell is effective in combat, but can be used to shape the terrain. When used on a creature, they will take 3d6 Force damage (+1d6 per level). This attack, only if it is using Force damage, will also cause the creature to make a CONSTITUTION saving throw with your spell save DC, and if it fails, the creature is stunned. The following can only be used once per short or long rest, and only if you cast this spell at level 3 or higher: You can use a bonus action to change the element of this spell, changing it's damage from to Force to: Fire, Lightning, Radiant, Cold, Thunder, Acid, Poison or Necrotic. If, for any reason the spell stops being cast, it will revert back to its original element of Force damage, and you cannot use this ability again until a short or long rest.
