Horn Drill is a Normal-type move with 1 power and an accuracy of 30%. It is a one-hit knockout (OHKO) move, meaning if it successfully hits, it will instantly faint the target regardless of their remaining HP. However, it cannot affect targets of a higher level than the user. Horn Drill is often considered a high-risk, high-reward move due to its low accuracy but potential to change the course of a battle by knocking out an opponent with a single hit. Like other OHKO moves, its effectiveness is further restricted by battle mechanics that prevent it from working on opponents with the Sturdy ability or those that have used moves like Protect.
