Hip Drop is a recurring skill in the Dragon Quest series.
Making its debut, Jessica learns this ability when she invests 48 skill points in her Sex Appeal skill tree. It causes 1.3 times the damage of a normal attack, and enemies can potentially just stare with hearts circling around them. Fat bats and Night emperors can also use this skill against enemies, as well.
While absent from IX, it can be learned through recruited Imps just by investing 3 skill points in the Kokau Magic skill tree. It deals 1.2 times the damage of a normal attack, and has a 50% chance of mesmerizing enemies. It costs 2 MP for the Imp to use.
Jade already has this skill when she joins the party, and can hit enemies for 1.3 times the damage of a normal attack, while potentially mesmerizing enemies. It costs 2 MP to use, just like X, and Jade can use it against the party when she's Jinxed, along with Vampire succubats and Supreme succubats.
