Arcane Cataclysm

Create a teal/blue, vision distorting Destruction wave, on the casters palms.

As part of the casting action or in another action that you maintain the spell, you may chose one of the following ways:

• Make a melee spell attack again a creature, dealing 1d10 damage of an element you chose (fire, lightning, cold, force). If you kill a creature with this spell, you may chose to overcharge it to desintegrate the creature and any number of items it is carrying. 
• Fire the energy at a target you can see within 30ft,dealing a random element of 1d6 damage (fire, lightning, cold, force)
• You start to destroy, break, or outright desintegrate a nonmagical item you touch. For each 1^3ft you take 6 seconds to affect the chosen target.
