SSR Nike and Cthulhu were the combo I was aiming for for Water. They have complementary debuffs that get you to -35% ATK and -50% DEF with Sniper Shot, plus overdrive reduction from Cthulhu. Jorm's debuff augments that to -45% ATK. Dragon King is nice but her abilities overlap with both Nike and Cthulhu's. Dragon King is good for teams that would otherwise be lacking the core debuffs. Otherwise she doesn't pair that well with the best Water SSRs.
