This build is highly reliant the gear. We'll use Lightning Rod to passively generate clouds as usual, but we'll use Blood Corruption(BC) to generate our metal shards this time. With Crimson Resonance as our talisman when we generate BC we'll also generate clouds. Using our clouds we'll use Floral Tempest orb to make blossoms to power Symbiotic Parasite and in conjunction with cloud skills generate Blood Reinforcement to survive our BC stacks. This allows us to stablize at 26 BC and slowly grow each round by 3 every round. Finally we'll use Thundercaller and Thunderous Bloodmist to scale our power and cloud boost to the moon and rain down constant thunderbolts on the enemy.
This build will eventually die when we make more than 16 parasites as we can no longer upkeep them, but hopefully the enemy will be dead by then.
