Aryas bolt of chaos

A ball of white energy coalesces in your palm and shoots out with tendrils of various elements pulsing out as it travels. Make a ranged Spell Attack against a creature of your choice within range. On hit, roll 10d6 of a randomly determined type. Roll a d6. The number determines if it is Acid, Cold, Fire, Lightning, Poison, or Thunder Damage. Due to its chaotic nature and its recent creation, this spell has a chance to go volatile. If the caster misses the target's AC by 5 or more, they take 3d6 force damage. The caster can choose to take a -5 penalty to the attack roll in order to choose the damage type of the spell
At Higher Levels: The damage for both attack and self damage increase by 2d6
