Horn Drill (Japanese: つのドリル Horn Drill) is a Normal-type one-hit knockout move introduced in Generation I. It was TM07 in Generation I.
Horn Drill inflicts damage equal to the target's current HP. Its accuracy is 30%. Horn Drill will break a substitute if it hits.
Horn Drill will not affect a target whose current Speed stat is greater than the user's current Speed stat.
The accuracy of Horn Drill now follows the formula below.
Acc = ( ( user_level - target_level ) * 2/256 + 76/256 ) * 100%
This forumla means that the accuracy starts at approximately 30% and grows by approximately 0.78% for every level higher than the target that the user is.
Horn Drill's efficacy is no longer based on the target's Speed; instead, now it cannot affect a target that has a higher level than the user.
In the Generation II core series games only, Horn Drill can be countered by Counter for maximum damage if it misses.
Generations III to VI
The formula for Horn Drill's accuracy is now:
Acc = ( ( user_level - target_level ) + 30 ) * 100%
Horn Drill's chance of hitting is now unaffected by accuracy and evasion stats.
Horn Drill can be used as part of a Pokémon Contest combination, with the user gaining an extra two appeal points if the move Horn Attack was used in the prior turn. It is also part of a Contest Spectacular combination and will give an extra three appeal points if any of the moves Lock-On, Mind Reader and Miracle Eye was used in the prior turn.
Horn Drill's accuracy is now displayed as 30%; however, its accuracy calculation remains unchanged.
