Well my friend, playing as a storm in solo battles especially a 1v4 is a bit of RNG. When I did this battle it took me 2 attempts. Really you just need to not stall the battle out for a long time. You're rocking Water Works gear I pressume? If so as long as you have a good athame and ring that give good power pip chance get 2 blades on and look to Storm Lord, hoping you critical you can blade and possibly tempest if needed. BE SURE YOUR DECK IS NOT CLUTTERED. Don't pack any single hits or anything you won't need. All I packed for that fight was 4 Colossal, 2 Storm Lords, 2 Tempest, 4 Storm blades, 2 Elemental Blades. Thats about it. Wouldn't bother with much else. Also if you get second, might as well flee and port back and hope for First. Hope this helps!
