When you cast this spell you summon a storm cloud above a creature and make a ranged spell attack. On a hit, you deal 10d10 Thunder damage, as well as 10d10 Lightning Damage. Your attack roll scores a critical hit on a d20 roll of 19 or 20. If it is already storming in the area you can add an additional 2d10 each of Thunder and Lightning damage.
* - (A palm sized Amethyst, and a Staff made out of Mahogany)
you should be aware that artificers generally cannot cast 7th level spells and that the chance of you missing this attack and just completely wasting a 7th level spell slot it just way too big, especially when compared to the accuracy of pokemon moves (i assume that this is based on a move from pokemon)
Thunder damage is meant to represent the damage dealt by extremely loud noises, so perhaps it is not appropriate for it to deal 10d10 thunder damage, already a little too much damage for its level
its range description is erroneous, as it does not affect an area
